Why is snow so hard to recreate? [i.e. why do they use "fake snow" for movies?] | I don't think it's so much about the creation as it is about the longevity of the flakes.

If you use fake snow, the flakes on their head will stay consistent between shots. |

Why are peanuts banned from schools but not workplaces? Does the danger of an allergic reaction decrease with age? | My kids school doesn't ban peanut butter. In fact we offer it as a choice with our morning breakfast program that I help run. We obviously have a list of kids that can't have it and the older ones know better.

What are septic tanks and what are they used for,more improtantly why do only America have them? | They are where sewage from your house goes to collect in tanks out by you yard or something.

The LF is a small patch of land where the soil bacteria can kill and outcompete... |
Why do certain Countries outside the US accept US Currency, and on occasion only accept US currency. Why target the US Dollar Specifically over other currencies such as the Euro? | The US dollar is the world's main international currency by convention.

It simplifies book-keeping for companies that do a lot of foreign business, and makes the transaction a bi... |
If our stomach acid is so strong, why do things that make us sick/give us food poisoning not get destroyed during digestion? | Many organisms thrive in acidic environments, or at the very least are able to survive in them.

In light of constantly unpopular Congressional decisions in the past few years, are we just a gullible public during elections, or is Congress experiencing something like a Group-think effect? | Neither.

The primary issue is that we, as a country, do not have a unified opinion on what we should be doing or where we should be goin... |
If energy cannot be created (or destroyed), how did it come about? | The total energy of the universe is exactly zero.

What, if any, benefits are there to staying on the gold standard? | Gold standard means money=gold. Many of today's finacial problems are caused by central banks literally printing money .

Look around in 2007.Also, m... |
How come cops still handcuff people that have been showered in bullets and are clearly dead. | Because it is good policy, kind of like a liquor store always asking for ID.

Why you blow on a flame to make it bigger and you blow on a flame to put it out. | As others have explained, you blow slowly to add oxygen, which feeds the fire. Fire triangle, basic chemistry, etc. It's a bit harder to explain why you blow on it quickly, but here's the simplest way I can do it. You're **not** simply cooling the flame. Let's say you're looking at a lighter. When you press the button ... |

What is the point of the anaphylaxis reaction. Why would the body try to protect itself by essentially committing suicide? | The issue here is that we tend to think of the immune system as the body's army, a group of soldiers that are charged with defending their home from attack. But that's wrong. The immune system is more like it's own civilization, doing the best it can to keep the local environment to its liking. It's just that the envir... |
Why do many woman say it's just as hard for women to find sexual partners as it is for men? | Here's how I see it. I could probably find a guy who would be willing to have sex on me -- he'd stick it in and he'd cum -- but it's hard to regard that as me having a sex partner. Chances are, I wouldn't cum, my major sexual stimulation point wouldn't be involved, and I'd essentially just be a fleshlight for his pleas... |
My 10 year old nephew wants to know, Where does sound go? Does it just disappear? | Let's do this in true five year old fashion. The air around us is made up of molecules and particles. These molecules and particles aren't too unlike rubber balls. If I were to throw a rubber ball, the movement I gave it - the energy - would cause it to go flying towards whatever is in its path. Sometimes it's more rub... |
Athletes that throw spears are fit, while those that throw neck-boulders are more of the bulky type. Why so? | So somebody's already explained why each type looks different.

Why can we HEAR our joints crack? How does sound escape the inside of our body? | Sound is a compression wave. You body's structure is relatively good at transmitting waves of this type, that's how sound gets from the air in your ear into the part of your ear that senses it.we don't know 100% for sure, but the leading hypothesis is cavitation. the motion causes the fluid in the joint to form tiny ga... |
Why does blood not stick to human skin like a permanent marker, but will stain things like clothes so bad? | It's not about the blood, it's about the material the blood is getting on.

Why transposing instruments (Bb Clarinet, French Horn, etc) work the way they do. | Actually, you're completely familiar with it as a violist.

Now, you want to read the same clef as you currently do, so you just write everything up a half step. That's what happens for the Bb transposition. Same thing... |
Why was salt so valuable in the past? | It simply takes a lot of energy to evaporate enough sea water to get a large amount of salt.

Meanwhile, saline salt was extremely cheap to pr... |
Why has every human being his own preferences and likings but every animal species seems to like/dislike the same things. | There are some universal tastes which I guess animals have too.

Why does it feel so good to figure something out yourself (riddles, hidden meanings) rather than say googling them? | When you learn, understand, or otherwise work something out, your brain releases dopamine, a feel-good chemical.

Being capable of l... |
Why are feral children often incapable of adapting to civilization? Are they permanently learning impaired? | A language theorist named Lenneberg studied this, and came to the conclusion that children have a 'critical period' from age two through to puberty where, if they don't learn skills such as language in this time, they'll never be able to fully grasp it later in life. It's debated as to why this is, but one commonly acc... |
When you're dehydrated, is it better to chug water fast or to drink it slowly over time, or does it even matter? | I've heard on a survival show that your body can only absorb like 1 liter of water per hour, so I don't think the pace at which you drink it really matters.

Why are "Romeo and Juliet" laws called "Romeo and Juliet" laws? | Romeo and Juliet laws decriminalize sexual contact between teens who are below the age of consent, but whose ages are close.

Why do we 'never forget how to ride a bike' ? | I don't think it's the act of riding the bike that we never forget. I think it's largely that, as we get older, our balance improves and we can control our bodies better.

Why did humans evolve mentally when every other species evolved physically? | Intelligence and teamwork turned out to be a viable strategy. However, it's worth noting that we do have some impressive physical abilities too. Our eyesight is absolutely fantastic, and we can run for distances that put just about any other land animal to shame. And all that while still being able to climb and manipul... |
Why are the vast majority of commercial airplanes white? | Lighter colors reflect sun instead of absorbing it, which keeps the plane cool while it's taxiing on the ground. Less need for A/C.I was told that the best color for aluminum skin is white because it helps to conceal the waviness of having parts fastened together with rivets. If you ever see a corporate jet painted bla... |
How is it possible to teach a person who is blind and deaf? | I'm surprised these people don't think they're being attacked half the time.

Some one who is blind and deaf.Deaf-blind people today can communicate using Tactile Sign Language. ... |
Why do various animals when petted respond by closing or squinting their eyes? Goes for some humans too. | As a human who sometimes enjoys closing my eyes while I'm being pet, here's a answer from one person.

Impossible to know if this is true for animals, re... |
If it's dark and you're being pulled over by the police but you might not like the look of them, are you allowed to drive to a crowded area before pulling over? | A good thing I like to do is if a police car is flashing the lights is to turn on my hazard lights so it at least knows I've acknowledged and will pull over. I like to do this especially on busy roads so I can pull into a service station or things like that. |
EIL5: the federal reserve, and why Ron Paul wants to get rid of it. | The Fed is a crucial part of our financial system.

But they are not ac... |

Why does the quadratic formula work? | Gonna assume you know how to expand out a bracket and all that. So if you have some equation like *^2*, it expands out to *x^2 + 2ax + a^2*. So if we've got an equation that looks like the second one, we know how to condense it down, which is what we do to figure out what x is when y is 0. For example, if we have *x^2 ... |
