What is the science behind TNT Pop-Its (Snap Bags)? What makes them explode when you throw them at something?	Inside the tiny bag is ~99.99% gravel or sand, the other 0.01% is a chemical called silver fulminate. It's a highly unstable chemical that ignites under any sort of friction ( by dropping, squeezing, or stepping on it). When the chemical ignites it creates a shockwave that travels faster than the speed of sound and that's where the "snap" sound comes from (kind of like how a whip makes its noise). This shockwave is extremely weak and that's why you can pop one in your hand and it wont hurt.
Why Israel does not like the Iran nuclear deal?	It's simple: they know Iran is full of shit.
The weird noise your eyes make sometimes when you blink, what is it?	It’s the tensor tympani muscle in your middle ear contracting. It’s sort of like the muscle pressing against the hearing bones in your ear creating a whooshing or rumbling sound
Why does time asleep feel the exact same whether it's four or eight or ten hours?	I believe it has something to do with the fact that you are not conciscious when asleep, and thus any kind of recollection of elapsed time is beyond what you're brain had been doing while asleep.
Red Cross told me my blood is super special because I am O-Negative, and CMV-Negative, and my 5 units of blood helped save premature babies, what is CMV-Negative, and why does it help premature babies?	Cytomegalovirus negative. It's a very common viral infection that normally doesn't produce any symptoms. However, it can be dangerous towards immunocompromised patients and can cause liver failure. By not having it you can't expose it to the premature babies, which have weakened immune systems. This reduces their chances of infection, which is good for obvious reasons.
How does Reddit make money?	Advertisement (as AlxeYo pointed out, you might have an ad-blocker on), sponsored links, and reddit gold.
why we can secure banking/investment accts online but we can't secure voting	The requirements are different. Most importantly, banking information needs to be tied to the person making the transaction. If any inconsistencies come up they need to be able to make sure they have enough identification information to trace the transactions back to the person who made them. This is exactly the opposite in voting. Voting has to be anonymous. Having anonymous voting but still being able to trace the inconsistencies back is a trickier problem. It's not impossible tho. The real big issue is that an election screwing up and a country having a tyrant running it who is willing to fix an election to win is far, far worse than any loss of money a bank might suffer. Electronic elections software has way more riding on it than banking software.
If Stephen Colbert is so marketable and millions of people watch Jimmy Fallon clips on YouTube, then why don't the networks move their shows to prime time?	these shows win against nothing. would people tune in every night when its up against football, voice, ncis, ect ect? I think they would struggle to garner as many viewers in primetime.
Christopher Nolan's movie, "The Prestige"	Eek - this is a tough one... I had to watch the movie twice to have it make sense... The Christian Bale character was actually a set of twins, but no one ever knew it - not even his wife. They take turns dressing as the assistant throughout the entire movie. One of the twins was in love with the wife, the other was in love with Scarlett Johansen's character. Hugh Jackman spends the entire movie trying to figure out how to copy Bale's signature move, and eventually turns to "science" as a way to do that. Eventually, he gets it to work, and kills off one of his clones every night. Besides trying to figure that out, he also blames Bale's character for the death of his wife, and all of the trauma drives him insane. In the end, he uses the clone machine to frame Bale's character for his murder. He then goes on a mission to destroy his life, and Bale's character is hanged for murder. The end shows the assistant leaving with the little girl, but he is actually one of the twins.
How is that the colors we see organize into a repetitive pattern (ROYGBIVROY...) while their physical wavelengths are linear (390-700nm)?	The issue is wavelength doesn't define color. Photons can be any single wavelength, but our eyes sense the number of red, blue and green photons (there is lots of overlap), so a single wavelength light will be one color, such as red, green or blue, that doesn't cover what you get when you have two different wavelengths at the same time. So Red and Green light added together is yellow, and your eye can't tell the difference between that and single wavelength yellow (since both cases are just equal amounts of red and green excitation of your eye. The special case is purple, that is red and blue without green, on the EM spectrum halfway between red and blue is green, but if you actually mix red and blue you see [purple](_URL_1_), this color is not on the EM spectrum and does not correspond to any single wavelength. It is different because your eye can distinguish red+blue+green and red+blue without green. To cover all the colors a human can see you need a [2D plane](_URL_0_), they don't map to a line.
Why can we see the xenon atoms in the IBM logo but not the atoms of the surface they're on?	For the same reason that you can't clearly see objects far behind the subject of a photograph. The background is not in focus. That is a simplified explanation, but basically still true.
What would happen to the United States if China called the debt to be paid in full within 12 months?	the debt is in bonds. which have a set maturity schedule. the bond holder doesn't get to dictate the terms. only the bond creator does.
What exactly happens to your debt when you die. Who is left unpaid?	All assets are usually frozen. The executor to the estate that is assigned by the state (usually identified in the will) must, by law, pay off all debt before any inheritance is given out. If no money or assets are left in the estate, the unpaid folks are out of luck !
Why hasn't NSA's "Prism" database been hacked?	A common feature of secure cross network scenarios is a 'data diode' which literally only allows data to pass on one direction. So even if some hacky malware does manage to get through to the secure system there is absolutely no way for it to send anything back.
Why can't huge companies like Google and YouTube beat ad blockers?	Google doesn't go to great lengths to prevent ad blockers for the same reason that Walmart and Target don't use draconian measures to stop petty theft. Sure, a big store could eliminate all petty theft if they wanted to - but not without inconveniencing and annoying legitimate honest customers. Same with ad blockers. It's not worth going to great lengths to fight ad blockers when it will just piss off the average user.
What would happen to the human body if it got exposed to the extreme pressures of the deep ocean?	rapid compression. if I had to guess... and this is a guess, your body would quickly fill less tightly filled spaces within itself. (intestines, heart, lungs, ears. rapid outgassing via anus, rapid color change of your skin almost akin to when you open a compressed water bottle and it makes condensation. like a flash, all your blood vessels etc would adjust. Not sure what color you would turn though, probably first white then red due to lots of vessels rupturing during the pressure adjustment. I would assume death would be in a matter of seconds. In other words very very uncomfortable.
. How does a knife cut through stuff	Every material has some amount of stress it can absorb before it gives way. Knives create a lot of stress by taking the force you apply and putting it in a very small surface area.
Why does everybody with Down's Syndrome look alike	Because those facial features are a symptom of Down's Syndrome.
Why do parents need to force their children to eat?	It's not about forcing them to eat. It about forcing them to ready right. Left up to children they will eat only candy and snacks. That's why parents want their kids to eat all their actual food on their plate (veggies and grains) before letting them go and eating dessert. The fact that some parents over proportion is unrelated.
why does it sting when I put my contacts in if I haven't slept much /well?	Eye gunk (Rheum) is kinda floating around our eyes while we sleep. When we first wake up, it takes some time/binking for that to go into the corners of our eyes which we end up wiping away. Putting contacts in shortly after waking up, this stuff gets stuck behind the contacts and irritates the eyes... Actually I have no idea why even if this explanation counts for anything... its only a bit of the explanation... (must be more blood flow in the eyes, making them more sensitive or something) I just hate putting my contacts in after not much sleep. Contacts/eyes suck. TR;DL: This is a useless explanation....why am I typing right now? Source: I wear contacts.
Why does Israel continue to build/expand settlements in Palestinian lands despite international condemnation?	Cause it does not care. It gets the USA to veto any action against it at the UN. The P5 countries: US/RUSSIA/CHINA/UK/FRANCE can put a magic veto on any action they don't like against a country they support. So the UN has really no power at all, just puppet bullshit and more money wasting. The are also the biggest weapons dealers in the world BTW Pretty much the same way Israel has nuclear weapons, still gets tons of money from the USA (which is illegal, can't give aid to nuclear armed countries) AND still tells Iran they can't have nuclear, although they themselves did not sign the Nuclear Non Proliferation Treaty AND do not let the UN/International agency inspect their nuclear installations (pretends they don't have any weapons and if you think Israel is doing anything wrong you are a Nazi anti-semite.
How do wild animals know to not drink salt water?	it doesn't taste as good as fresh water. that's the same reason you wouldn't drink it if no one taught you.
Why does acne hurt, and what is the actual white puss from?	The acne hurts from the inflammation. The majority of puss is actually not dirt or dead bacteria. It is your own white blood cells (mostly neutrophils).
If a women drugs and rapes a man then becomes pregnant, can she be forced to undergo an abortion?	Of course not. Why would you think this?
What it would take to shut down the internet in the US	Every country has an equivalent of the UKs peering points provided by "telehouse" and "telecity". This is where Internet providers connect to each other, and to international carriers who in turn connect to other Internet providers. The US will likely have many of these, so in order to stop all Internet traffic from the US you'd have to take out these peering points. Edit: Grammar
How does gas compression work? Highschool chemistry taught me that various states of matter are the same thing just molecularly tighter. Why is a compressed gas not just liquid?	Super compressed gas does become a liquid for most gasses (though I think a few gasses like hydrogen get kinda funky there instead). Compressing gasses brings the molecules closer together, but most gasses need to be compressed quite a bit (or cooled down a lot, or some combination of both) before they actually transition to a liquid phase. Check out "phase diagrams" when you get a chance, they show the combinations of temperature and pressure for a given material where the material is a gas, liquid, or solid and can help you to see where things will switch from one to another.
How does the box office work? For example Interstellar cost 165m to make but it only grossed 173m. How in the world does a cast get paid with 8m?	Also worth noting that the profits from a movie don't end after a month of release. DVD sales, rentals, licensing agreements with streaming services etc all create revenue after the initial release of a movie.
If your eyes don't have pain receptors, why does it hurt to look at the sun?	It is incorrect to suggest eyes don't have pain receptors. Some structures in the eye can be among the most sensitive to pain. The retina itself may not react to damage, but there are cells in it which (While photosensitive) are not used in vision. Instead, it appears some of these cells function to stimulate the trigeminal nerve, creating the sensation of discomfort. In fact, even in blind people photophobic (light avoiding) behavior can be stimulated, such as responses in the iris. This may also be why closing one eye reduces the discomfort, as you are effectively reducing the signal.
If I drink half of a Five Hour Energy, will I have half the energy for five hours or the "full" amount of energy for 2.5 hours?	There are multiple active ingredients in the stuff. Each of them has a curve that initially goes up relatively quickly and then fades slowly as your body processes it. If you take half, the strength of those curves cut, but they are not squashed in the time dimension. That said, it takes a lot longer than 5 hours for it to be 100% out of your system. The "effectiveness" ends when the strength falls below a certain threshold. With a lower dose, that would happen sooner. So, it would be weaker at its peak _and_ not last as long.
How do illiterate people in developed countries function?	Being illiterate doesn't necessarily mean that you can't read at all. A lot of times means that you can sort of read but you can't comprehend a lot of what you read. There are plenty of kids in school who can say the words that are on the page, but they don't really know what it means. If you're on of those people, you can find a job that has minimal "reading" and what does need to be read is often written in very basic language. What you said about birthday cards? Well, they probably know how to to write "I love you, Jonny." They probably also know what that means. You might be able to recognize the pictures on food that you're buying. You may even be able to figure out basic math to know that the numbers on the shelf of the grocery store add up to less than what you have in your wallet.
Why were the Star Wars prequels considered so bad?	Personally, my question would be more along the lines of "why were the original Star Wars movies considered to be so good?" They had awful scenes and dumb humor throughout. The greatest thing about Star Wars IMO was the universe it created. Jedi, lightsabers, space travel, all amazing. However, breaking it down scene by scene I don't love them.
how does a thermal explosion cause a human to get knocked back, as often seen in action movies?	Movies aren't always representative of real life. Action movies even less so. Of course, it's possible for an explosion to knock people back. Because of the rapidity with which explosion take place, they almost always create a shock wave. The problem with being knocked back with the shockwave from a thermal explosion, however, is that the shockwave is likely many thousands of degrees. Of course, only being in contact with it for a short time, you wouldn't necessarily be burnt to death (unless it was a really hot bomb), but it certainly wouldn't be as clean as movies lead us to believe.
Why are metals like bronze harder than the metals used to create them.	It has to do with the different phases that form in alloys. Basically two materials form a matrix that creates a hybrid grain structure that is stronger than the homogeneous materials themselves. It is a bit complex, but think about it like concrete. Concrete is really made up of sand, pebbles, and rocks. Each on their own isn't very structurally sound, but together they all interfere with each other's movements, making the whole much stronger than any one part. Tried to keep it high level, but I can elaborate if anyone likes.
if we Americans strive to separate church and state, why are so many polling locations in churches?	Why cant they be? The separation of church and state just means that there can be know government endorsed religion. It does not mean that politicians cant be religious or that government functions couldn't be held in a church etc.
What is making the prices of houses in the UK so high? Is there any hope of fixing this issue?	There are a finite number of houses and a finite amount of space. So as population grows and more and more people want houses... prices rise. There is no solution save a good plague or a good war. Need to get rid of the bodies or acquire more land.
how does "old faithful" erupt so consistently	[It doesn't](_URL_0_), at least, not anymore. The 1983 Borah Peak earthquake set the schedule off balance, and another in 1998 really changed things up. Geysers are fed by underground rivers that lie above a pool of magma. After an eruption, the water begins to fill back up and the pressure increases. Pressure causes the water to be superheated (over boiling temp, like a pressure cooker ^hello ^NSA!) by the magma and, like a volcano, the turbulent pressure brings it to the surface. When it reaches the surface, the pressure inside drops, which causes the superheated water to become volatile. It vaporizes and shoots out of the geyser like a rocket. [Mythbusters](_URL_1_) has an example of superheating that offers a pretty neat visualization.
Why do Black Lives Matter protesters only show up for police-involved shootings? Why are black-on-black shootings ignored?	The protesters aren't there just because people are dying or because they hate "shootings". Black lives matter is about a particular issue - injustice at the hands of the people / systems that are designed to protect us all equally. You might as well be asking why the same people aren't also showing up for events about diabetes and heart disease since these kill a lot of black people. Further, black on black violence has been the subject of many conferences and events. It doesn't receive much coverage in the media.
Beer and rate of consumption...	2 a day would be healthier. When you drink 14 at once, your body is going to struggle to deal with it at once, you're taxing your system a lot more. While a couple a day, your liver can deal with that without a bunch of backlog, you're not going to be sick, not going to be dehydrated etc...
When momentarily walking past fumes (exhaust, tar, etc) is it better to breathe normally or to restrict your breathing for a short period (thus reducing oxygen intake)?	Hold it. There isn't harm in short periods without breathing, so the down side is nil. The stuff you're breathing probably isn't going to hurt you if it's just a whiff, but there's more potential harm from it than from held breath.
How is the Universe expanding if gravity pulls things together?	Wouldn't physicists like to know. But seriously, they dont know. At this point, all we have are some theories. Mainly, dark energy. Basically an unknown, undetectable force that pushes on everything in the universe. Locally, its not strong enough to overcome gravity, which is why stars, planets, orbits, galaxies, etc. still exist; but on a cosmic scale, it is strong enough to push all the clumps of mater (which are basically clumps of gravity), away from each other. It's also worth mentioning that, since dark energy expands space itself, and isn't technically moving anything, the expansion of the universe is actually faster than the speed of light. Some galaxies are moving away from each other so quickly, that light from one galaxy would never be able to reach the other, because it cant travel fast enough.
How does the placebo effect actually work?	You have substances in your body that are chemically very similar to the drugs that are prescribed by physicians. The reason drugs work is because we have receptors that drugs may biochemically bond with. In the case of placebo, it's believed that the suggestion actually activates the body to create and mobilise the natural substances to bind to the receptors. So, for example, our bodies make natural opioids (dynorphins, enkephalins, endorphins, endomorphins and nociceptin) which are natural analgesics. In the example of pain, a placebo primes the individual to create their own opioids. RadioLab had an excellent programme on this, [podcast is here](_URL_0_)
Why do we find "sweet" things so pleasurable? Even other animals really seem to enjoy sweet things.	Sweet implies calories, and animals need calories to survive. Animals evolved not knowing where their next meal was coming from, so it benefits them to eat as many calories as possible while they can. By making calories pleasurable, it creates a desire to eat them.
how do multilane highways reduce traffic if they merge to fewer lanes without oppurtunity to turn off?	They alow the people driving at a faster rate to get ahead of those that are driving at a slower rate and causing the traffic to collect behind them.
Canned meat not needing refrigeration?	Part of the canning process is heating the cans after they are sealed. The heat kills any bacteria present in the contents, and the sealed can prevents any new bacteria from getting in. As long as the can isn't compromised most canned goods remain safe almost indefinitely (although many won't taste good after a long time).
Why do the members of the Whitehouse press pool yell out questions to the President after they have been told that no questions will be taken.	That's what you do as a journalist, ask questions. You wouldn't be doing your job if you kept quiet. It's pretty normal in all settings like this. There's a big difference between "we asked, and he didn't want to answer" and not asking at all. I don't know if it's ever worked in a presidential press conference, but it certainly does happen that someone will decide to answer a poignant question even though he didn't want make any comments.
Why do we use the "Qwerty" keyboard?	You can wiki for more. The basic story is that English has a number of common letter pairs. On old typewriters these letter pairs were often so close together that the arms (that "type" the letters onto the page) could swing in and jam if the operator was too quick. So the Qwerty board was developed. It breaks up the common letter pairs so that jams happen less frequently.
How do companies like EB games and Gamestop make money when the game/console creators sell the game online for the same price?	Source: I was an assistant manager at Gamestop, and I worked there from 2011-2014. A very large majority of their money comes from used games. We paid $54 for every $60 new game we sold. We only made about $25 off of new consoles. The only thing that keeps them afloat is used games. We would make $35 off a used game that recently just came out which is more than a new console and new game combined.
What would happen to the financial stability of the United States if foreign governments suddenly stopped investing (and reinvesting) in U.S. treasury bonds?	The majority of Treasuries are held by private individuals or corporations, or by the U.S. government itself. As far as I am aware, foreign governments to not hold a significant share of the debt, but foreign central banks account for a large chunk. If those central banks decided no longer to buy U.S. Treasuries, then: - Demand for the bonds would fall. - Prices would fall (interest rates would rise) - Other investors would buy more bonds at the higher interest rates, but not enough to offset the rise in rates. - The Federal Reserve, if it thought that rates had risen too much, would sell bonds to lower the rates. - Life would go on, but it would cost the U.S. more to finance its debt. Depending on how much more, this may cause medium-term sustainability issues that might oblige it to cut deficits, which would hamper the ongoing economic recovery. Of course, a scenario in which foreign central banks outright refuse to buy U.S. Treasuries would be one in which other things had changed as well.
Why there is such a variance in the human phenotype, as compared to other species?	the same reason asian people tend to look the same to a white person. they're so different from us that we overlook the subtle differences that are in fact obvious to someone or some animal of the same species. e.g. they do vary, you just don't notice it because you aren't an elephant. the point about human evolution that /u/lithuim brings up below is also a good point to add, humans specialize in recognizing subtlties in other humans, irrespective of the points above.
If poverty is so bad in an area like in ghettos or in Africa. Why do people so readily continue having children only to be born in to hardship?	You think of them as another mouth to feed because you're a middle class guy in a nation with child labor laws. If you were in the developing world you might think of them as another pair of hands to help with the work or something to exchange for goods in a wedding. Or you might simply be uneducated with no access to contraceptives and no other activity to bring you any joy.
why aren't there electoral systems that allow negative votes?	There are several different voting systems that allow you to downvote certain candidates. However it is usually not compulsory. However the most effective way to keep people from voting strategically is to use a ranked voting system where you sort the options from most preferable to least preferable.
How does changing electricity companies work when it travels in the same wires?	See the electricity network as a huge tank (the wires). There are some things that need to be done: the tank has to be filled with electricity, the tank has to be maintained and the electricity has to be distributed to the people. These things can be done by different companies! There is usually only one company owning the network and maybe a few filling the tank, but there can be lots of companies distributing your electricity. They can all make a difference to eachother by offering you deals with gas or other services, by making different arrangements with the owner of the tank, ... That way you get better competition and a fair price for both consumer and producer.
Why do my mom's ashes make a weird sound?	> What happens to the bones during cremation? If I had to guess, it probably is the hard, remnants of bone hitting the inside. That, or ghosts.
Why do we have fingerprints, why are they located on our fingers/hands?	"Fingerprints" are actually NOT only on your fingers and hands but over your entire body! If you look closely at your arm you'll notice hundreds of tiny lines across your arm, this is most obvious near your elbow. These are actually the same lines as your fingerprints. [Here's an example of what your skin looks like under the surface](_URL_0_). Notice the waves in the bottom layer? Those exist to increase the surface area between your skin layers and this makes your skin much stronger and keeps it anchored in place. On the surface those look like tiny lines which we call fingerprints. The reason why they're more pronounced on your hands (and also your feet) is because the skin in those areas takes the most abuse and has to be the strongest, so the lines are more pronounced.
How exactly does the counting for total karma work?	Keep in mind that self. posts don't add anything to your karma count.
How are "generations" measured? Where is the cut off?	A "generation" is a vague unit of time, so it depends on the context. In genealogical or biological terms, it is strictly the parent/child measurement, so yes, you would be in the same generation as your cousin, since you share the same percentage of genes of your grandparents. In a sociological context, "generations" are defined more vaguely as the group of people who grew up and lived together in similar circumstances. It starts at a relatively arbitrary point, in america it starts with the 1885-1900 generation, "The Lost Generation", The people who went through WWI and then the roaring 20s. Then the kids born in the next 20-25 years or so are the next generation, "greatest generation", then the "lucky few", "baby boomers", "Generation X", and most recently "millennials". The generations are usually named after what they do when they're aged 25-50, not when they're born. Sorry if that was a shitty explination
What is the purpose of humans having emotions?	Emotions guide us in the Darwinian process of the survival of the fittest. So love makes us bond with partners and family to help us survive and propagate while hate guides us to strike down competitors etc.
How does sand become glass?	Quartz sand doesn't become glass. It becomes fused silica, but you'd need an oxygen jet in your campfire, since silica won't melt until around 3,000F degrees. However, if you first mix sand with other chemicals, borax, lime, or baking soda for example, the quartz sand will dissolve in the melted borax etc. That way you only need glowing-red temperatures to get glass. Typical cheap window-glass is not quartz, it's "soda lime glass." And Pyrex cookware, that's borax-silica glass.
how do people graduate/finish school early	They don't complete 12 years of school, that's how. They do some school, and everyone involved agrees it would be a waste of time to have them sit through the same stuff as everyone else, so they skip them past several grades. 16 isn't really that crazy, I graduated high school at 17, and I went through every grade. Someone who graduates then could have just skipped some elementary school grade, or started 1st grade when they were 4, instead of the more normal 5. People who are younger just skipped more grades, or accomplished the requirements for graduating in less than 4 years, which cuts out a year.
how does CPR help someone who has been drowning?	I'm not a doctor, just a paramedic, but this is my basic understanding of how it works. Not all drowning victim have water in their lungs due to involuntary laryngospasm. But either way, the lack of oxygen to the brain and other organs causes unresponsiveness and cardiac arrest. Once the person has been removed from the water, cpr is performed to reoxygenate the blood and circulate that oxygenated blood through the body and to reperfuse organs. If you're successful, the body will start to cough up and remove the water that's in the lungs. Also, the lungs can absorb small amounts of fluids on their own, getting rid of the last bit of water creating more lung surface area to exchange gases.
why it takes less time to fly from west to east compared to flying from east to west	In really high altitudes there is moving air called "Jetstreams. In the northern hemisphere the jetstream generally moves from west to east. The planes can ride this jetstream giving the plane more thrust, vs if the plane travels east to west it has to overcome the drag created going against it. Think of it like a river. It's hard to paddle upstream but not down it.
Why do most live performers remove their in ear moniters when they perform? If it affects their performance, why do they wear it in the first place?	> As a professional musician for over a decade, the simple answer is this: In-ear monitors are excellent for keeping a fine tuned ear on what is being played, hearing click tracks, and getting cues. When someone takes out one (or sometimes both) of their in-ears, it's to either REALLY hear the ambient sounds around them, more accurately hear the crowd, or just as often, simply get a break from the (necessary) loudness directly in their ear. Actively listening to what's piped into your in-ears is what keeps musicians on key/on tempo. Taking them out gives them a break from the audio assault, and lets them engage with their actual surroundings instead of being in an isolated audio environment. From /u/jayrobhearthrob 's reply. It deserves to be a top level post but he says he doesn't know how to Reddit, so I'm helping.
How can people not get source code for a game even though they have the exe and files	The .Exe just contains the compiled code, which is pretty hard to reverse engineer into source code. This compiled code is what the computer actually reads and for the most part is just long strings of numbers and next to impossible for a human to read fluently. The problem with reverse engineering compiled code is that a lot of information is lost during the compiling process. It just becomes setting, moving and copying data from other places in memory. What those numbers actually mean is lost pretty quickly.
How do forensics assess whether someone was raped before or after being killed?	Rape tends to damage tissue a lot. If alive when damage is inflicted, the body immediately reacts to the damage in various ways, causing bruises. Plus when there are rips and tears, the man or woman who has been raped will bleed if alive. If dead, there won’t be any bleeding because the heart isn’t pumping, and microscopic changes that occur as the body reacts to injury won’t be present.
Why do some computer mice cost as much as $120?	Because money goes into design, research of technology, parts, marketing and ofg course lots of profits. When people spend a lot of time playing games, they want their connection the the computer, of which a mouse is one, to be the best.
How do the mico transactions work in the new Battlefront, and why is everyone freaking out about not being able to play as Darth Vader? Noob here.	Only a couple of heroes are unlocked by default, the rest have to be bought with in game money. You can earn in game money by playing the game or buying it with real money. many people feel the rate at which you earn in game money is reduced to such a level as to be frustrating to obtain and that this is done intentionally to force people to buy in game money with real money. Darth Vader is the most expensive hero and as one of the most popular character players feel that EA is trying to capitalize on certain heros popularity as another lever to push people to spend more money on the game. All of this is compounded by the fact that this game is a full price game. A number of people have said if this were free to play they may be able to accept this approach (even if they don't particularly like it) but since they're paying full price they expect all unlocks to be reasonably available without any further purchases.
What is the joke behind "Runway 37"	Runway numbers only go from 1-36. They are basically numbered for their magnetic heading (0-360 degrees) divided by 10. _URL_0_
Why do scratched CD's skip while playing in my car but don't skip when playing on my laptop?	Some players are better than others at ignoring the scratches. It has to do with the quality of the laser and/or sensor reading the disc. BTW, a light application of Mother's Mag Wheel polish does wonders for making scratched CDs easier for most players to read.
How does a gun protect me in my home when I'm supposed to lock it in a safe?	You put the safe near your bed, if it's a wall safe above the reach of a toddler, and you have the muscle memory to enter the code and load your gun quickly. If you're actually concerned with home safety, you probably have a security system. That will wake you up with plenty of time to access the safe, get your gun, and assess the situation. Prior to the incident, you teach your children about gun safety. Ask anyone about the age of 50 where their parents kept their guns. The answer is likely in a drawer next to the bed and a shotgun near the door. Yet, it's only recently that the spike in accidental shootings has arisen. Meaning the variable factor is either gun knowledge, or media portrayal, not the fact a gun was in the house. I grew up around and handled guns all my life. I never once came even vaguely close to accidentally shooting someone or being shot. Because I respected the guns, and was taught to handle them properly.
How can Valve get away with cutting prices as much as 70% on Steam for mostly games they didn't even make? Are external game companies not getting really pissed off from missed profits?	Valve has to clear such sales with the publishers who are making the money from those sales. If your wondering how these sales work: Game X costs $10 but only sells 5 copies a week. I cut the price to $2 and now it sells 50 copies a week. I am going to make more money despite the price being lower. Valve knows this works, publishers know this works, and so the Steam Sales are a win win
Why haven't we seen any 90s Nick Game Shows (Double Dare, Legends of the Hidden Temple, Nick Arcade) rereleased? Legality issues?	You don't normally see any game shows rereleased. A big part of their profitability is contributions from sponsors, which don't continue paying out in reruns and syndication.
why does congress have the power to completely alter a bill, changing the contents and even title, on its way through the house or senate? Why was this power created? Why has its apparent abuse not caused removal of the power?	Congress, and only Congress, has the power to choose each and every word of a bill. This includes the power to edit the bill before voting, and the power to vote on the final bill. If Congress couldn't do this, who would draft, edit, and pass laws?
How does the brain decide what little stupid things to remember, like what someone said or a song you heard once?	it's mostly based on the situation you're in. even if you just barely notice a balloon in the furthest corner of your view your brain could go like 'you member the time, you had that stupid little baby balloon? i member'
Ir Syrian refugees are displaced by war, homeless and unable to gain access to the basics of modern life, how are they able to travel to the US?	The UN has many charters on the human rights of refugees, the Syrian refugees fall well into the categories protected by this charter. They are getting to the US in all kinds of ways but mostly on transportation sponsored by private citizens, the UN, and the US government. Its the same with other countries, Canada has a program in place to allow groups of private citizens who raise $30,000 to sponsor a refugee family, the government will pick up the rest of the tab.
Why are so many rap/hiphop songs still about how good the rapper is?	Well, don't forget that rap has evolved to something of an art form. The same idea from the early days applies: rapping about dominance IS dominance IF you do it well. It's really just a platform on which you can do cool shit with the rhymes and good wordplay. However, if the rapper can spit something really innovative and smart in an I'msogood song, then it gains extra value because so many rappers have done it before. If you can make such a song, which is easy to compare with other similar ones, actually sound rad and have really good rhymes, then you are indeed a quality rapper.
Christians of ELI5: Why has our God stopped talking directly to people as He did in the Bible?	I grew up in the church and the way it's always been explained to me relies on an understanding of the Trinity; you have God the Father, God the Son, and the Holy Spirit. With the exception of some small windows of time, one of these three has been "present" on the Earth at all times. God the Father was present before He sent His son. Shortly after Jesus ascended into Heaven, the Holy Spirit was sent to occupy Earth. You'll notice, if I'm not mistaken, that all the instances of God audibly speaking to humans (with the exception of speaking to Jesus) are found in the Old Testament. So, the short explanation is that God doesn't talk directly to His people because the Holy Spirit is here now to interact with us and the Holy Spirit rarely, if ever, audibly speaks to humans.
Why don't Christians celebrate Jewish holidays?	It is worth noting that it was not until 1965 (20 years after the Holocaust) that the Catholic Church (as part of the Second Vatican Council) ceased to hold Jews collectively responsible for the crucifixion of Jesus. Christianity has a history of more than a millennium of anti-Semitism which it has only recently abandoned. Historically, Christianity has been intensely hostile to Judaism and has regarded it as a grave and unforgiveable moral failing for any person to refuse to convert to Christianity. That kind of history does not incline Christians to celebrate Jewish holidays or indeed, the holidays of any religion other than Christianity, which of course they believe to be the one and only true religion in the world, accept no substitutes.
As a Canadian, I cannot understand why someone wouldn't vote for Ron Paul. Please explain the main reasons people disagree with him. I have made a list of pros and cons inside. Please add to it.	You're assuming that your list of "Pros" are shared by everyone, and that's not true.
Why can't we use a game controller to pilot real helicopters?	You would need to add buttons for things not normally accounted for in a video game. Its not a bad idea, Drone pilots use game controllers because they are easy to use. When you are actually in the plane there are a bunch of feedback systems and gauges that need to be easily accessible, visible, and tangible throughout a flight. You would end up with a controller about as complicated as the cockpit already is. There is an entire area of engineering called human factors engineering focused on designing things to reduce human error, and aviation is a huge area for them. (Just in case you wanted to google something to read up on what is done about simplifying design)
Three Mile Island accident	Simple wikipedia does a great job at summing up the disaster. [Simple Wikipedia on Three Mile Island.](_URL_0_) Not exactly at a 5 year old level, but very understandable, as I didn't know quite what it was either.
What is the "Burakumin problem" in Japan?	In the past, those Japanese whose work involved death (undertakers, knackers, etc.) were, for religious reasons, the "burakumin" a caste of "untouchables", despised and banned from many aspects of public life. And this discrimination continues even today against their descendants. It is said that one of the major sources of income for private investigators in Japan is discreetly checking for burakumin ancestry in potential employees or romantic partners.
How haven't sloths died out yet?	There are quite a lot of leaves for them to eat, plenty around to keep the population up, and they have sharp claws to ward off predators. Sloths can fuck you up if you aren't careful, as can most wild animals. They have slow metabolisms and usually move slow, hence the stereotypes, but they are doing just fine in the wild.
Why does flame make a noise when it is blown on?	Sound is just the movement of air molecules. When you blow on a flame the sudden change in air temperature creates a small pressure wave (as warmer air is less dense than cooler air) that you hear as audible sound. Its like mini-thunder
Why is GIF still the standard for animated image files rather than APNG or MNG?	Do you remember when America tried to go metric? It's kinda like that.
Why are older Jurassic Park movies more realistic than the newer ones like Jurassic World, do they not have the budget to get animatronics?	Jurassic Park looked so good not because of the animatronics, but because of Spielberg and the lessons be learned in the production of Jaws, which also used an animatronic shark. In addition to using night scenes and simply quick cuts, his understanding of the capabilities of special effects led to the development of his own style, including the Spielberg Face. This meant a close-up of your actor or actress as they saw the T Rex, instead of showing the T Rex. What you don't see clearly in broad daylight makes it scarier.
Why are the gender divisions in choruses? Wouldn't you get a fuller sound from integrated choruses?	Also, it's much more challenging for individuals to stay on pitch and in tune when surrounded by others singing different tunes. Keeping the voices together helps everyone song the right notes.
why do older generations tend to "double click" everything on computers?	Have you ever gone to open a file on your desktop? Open up a file in your hard drive? All of those require double clicks. And now that I said that, I think you might be referring to then constantly clicking something after the first double click. My suggestion? They're just old and don't realize they already clicked it or they're impatient and tired of waiting. Which is kind of ironic.
What is with all the gold-buying shops popping up all of the sudden?	The price of gold isn't at the highest ever, but it's pretty close. And people are still in a bad state so selling that gold is more necessary then it was in other times.
How a country's mortality rate can be anything but 100%	Mortality rates are the number of people that die each year out of a sample of one thousand. Obviously they will all die eventually, but they won't all die in the same year.
Why is it illegal for people to take photos of someone without their consent public but the paparazzi are allowed to take photos of celebrities and people in the spotlight	I don't think this is a true statement, I think (and it depends on the country you live in..) you can take photos of someone in a public place... But there can be a restrictions on the publication of photography.
Why is deodorant only okay to put on your armpits?	If it's only a deodorant, other than maybe leaving visible stuff on your skin, it's not a big deal. Many deodorants are also anti-perspirants which is a drug that produces a reaction that prevents you from sweating in that area. It's not a good idea to do that all over because your body will have a more difficult time regulating temperature.
Why would I want my food to be antibiotic-free?	Antibiotics are NOT needed to stay healthy. The name itself mean "Against life" they are used as a extreme measure to combat infections in the organism. In fact ingesting doses of antibiotics without need can make you ill. However that's not the only reason. First of trace antibiotics on meat can translate to a decreased effect of the actual medicine when needed. The indiscriminate use of antibiotics has lead to the now actual problem of creating bacteria resistant to it. Which is bad because they are much more difficult to deal with. Beside all that the use of antibiotics on the meat means that they were given to the animals to prevent them from getting ill from the poor and often unsanitary conditions they are made to live in.
How did they produce and put Zyklon B into the cans without killing the workers making them, when it reacts being exposed to oxygen?	Zyklon B was produced in pellet form which only released a gas when exposed to water and heat. The pellets could be handled in relative safety otherwise. Also, materials which cannot be exposed to oxygen could be mechanically canned in sealed conditions where air wasn't able to enter. Consider compressed CO2 canisters: Clearly workers aren't all in a room full of CO2 stuffing them full with their bare hands. Technology exists where materials in one tank can be transported into other containers, via what are typically called "pipes".
Why does shampoo not lather up well when you shampoo for the first time in a while?	My sister told me a long time ago that dirt is the enemy of suds and that stuck with me. But it's basically true. Your hair has oils that are important to its structure. Those oils allow dirt to cling to it. Shampooing strips away those oils and thus the dirt. but remember dirt is the enemy of suds so you won't lather up the first time you do it. That's partially why shampoo instructions say to do it twice, to waste more product and to make sure your hair is actually clean. The second one will probably lather up considerably. Alternatively if you wash your hair too much it will always lather but you are doing considerable damage to your hair.
Why is Toys R Us the company responsible for the debt required to buy itself out?	Because the old management team agrees to sell the company to the new management team. This is known as a 'friendly' deal. The new management team, who are technically 'employees' of the private equity team, arrange for the debt too be paid by the cash flows of the company. ELI5: your dad owns a restaurant that produces $1000 of profit per month. Your dad sells it to a friend. That friend goes to a bank and says, "I'm buying a restaurant and I need a loan. I will pay you $750/mo and that cash will come out of the profits of the restaurant." The bank says, "OK, we have looked at the finances of the restaurant and we think this is a good deal. Here's the money. *HOWEVER*, if you can't pay the loan, we are going to take the restaurant from you and sell it at a bankruptcy auction."
why are most if not all of the zippers on my clothing made by the brand YKK?	About half the zippers manufactured are made by YKK, a Japanese company. Zippers are finicky and YKK makes reliable zippers. One reason it has managed to stay on top of the game is that it controls almost the entire manufacturing process, from smelting its own brass to making the final product, which guarantees it can keep making reliable zippers and has the added bonus of helping to hide its corporate secrets from competitors. There are some competitors which are cheaper, mainly in China, but the zippers break more easily and a lot of the developed world is wary of lax regulation in China and don't want lead in zippers. Additionally, starting a zipper manufacturing company would take a lot of capital and you would have to get a pretty big market share to make a sizeable revenue stream, so there are high barriers to entry. Here's an article that goes into more depth: _URL_0_ tl;dr: YKK makes good zippers, controls the whole process, and it's hard to get into the zipper game.
How do games with 2-bit color have transparency?	One of the four "colors" is allocated as transparent. There's another bit that can say what transparent should be represented as, which in Pokemon's case is represented as white. So for Pokemon, the color scheme is not white, light grey, dark grey and black. It's transparent, light grey, dark grey and black. Transparent is represented as white. Backgrounds don't need transparency, so they can get the full white, light grey, dark grey, black color scheme.
Why aren't laptop graphics cards removable like ram or hard disk?	Graphics cards produce a lot of heat, so upgrading one might lead to a situation where the GPU puts out more heat than the cooling system is designed for. And to save on costs and space, most of the time graphics cards are soldered into the motherboard instead of creating multiple unique sockets, or the laptop just uses the integrated graphics card of the processor.
How is it that game designers can make better looking games over the lifespan of a console (Xbox, ps3) yet not change the hardware?	Because they learn more about how they can use the hardware over time. As they experiment and learn it's capabilities and limitations they can make it do more and more awesome things. Just like how skateboarders learn how to do more complex and cooler tricks over time with the same boards.
Why is it that bookies can survive by simply taking peoples bets. You would think that on a game like the superbowl a bookie would have a 50/50 chance of turning profit or losing a ton	Bookies make money because they don't pay even odds. All the bets are placed in a pool, and then the bookie's fee (take) is removed. The rest of the pool is used to pay out the bettors for whichever team wins, proportionally to each bettor's wager.
