Bubbles that in a carbonated liquid (like soda) would escape are trapped in as the candy hardens. When they come into contact with saliva, the candy starts to dissolve and break, which allows t...

Why do humans tend to think red and blue are opposite colors?
[ "Primitive man would only have a single dichotomy when it comes to those colours, temperature. They would see red and think of the sun, fire, embers, fevers, infections, blood, etc. All of which are warm or hot. They would see blue and think of the sky, water, snow, hypothermia, corpses, etc. All of which are cool ...
[ "They are handicapped by lacking the ability to distinguish different colors. Red looks like they know red to be, but it might also look like green." ]

How are random numbers generated by computers?
[ "They plug a \"seed\" number into some equation and give you the output number. Usually the seed is generated based on the time, since that is guaranteed to be unique. Most of the time programmers can also manually set the seed. This of course makes it less random, but is useful for debugging because otherwise you'...
[ "What do you mean? Your question needs to be a bit more specific. Are you asking what it is? Or how it's set? Or how the payments are made?" ]

How come diamond-companies are allowed to control the number of diamonds in circulation, without being a monopoly?
[ "The **are** a monopoly. DeBeers is very much in violation of the various anti-trust statutes in the US. The problem is that they aren't _based_ in the US and their executives don't come to the US, so the US can't do anything to stop them. They operate out of countries that allow their business practices and, since...
[ "Legal monopolies are companies the government has sanctioned to be the only one to provide a certain service in a certain area. This tends to be things like utilities (water, buses, and electricity), although it can be almost anything. These companies can still make a small profit, but are *strictly* regulated. Il...

How does starting a sentence with a short filler phrase like "yeah, so" give you time to think of an answer as opposed to just being silent for that second?
[ "You'll have time to think in both cases. But if you fill the time to think with something, even empty phrases, you will get the attention and lesser chance of someone interrupting you." ]
[ "To let you (the listener) know that they are still talking. In a polite conversation, when one person is silent that is usually seen as permission for the other person to talk.

Why does the electricity in some cars get cut off when starting the engine?
[ "The starter motor draws a lot of current, enough current to reduce the voltage output from the battery. Since electronics sometimes do wonky things when operated at lower than necessary voltage, it's better to just disconnect them for a couple of seconds while the car starts." ]
[ "Without the electronics being computer-controlled it becomes difficult to essentially turn off the light with a timer that starts when the car is turned off. It'd be easy to just turn the lights off automatically when the car is off but there's cases where you might want to keep the lights on without the keys in t...

Why are the majority of boundaries between US states perfect straight lines?
[ "There are two types of boundaries: geographic, and and political. If the boundary is squiggly, it's a river. If it's straight, a group of people sat down and argued over it until they agreed, then drew a straight line. In Europe, those political boundaries were decided by centuries of war and incredibly detailed p...

If I get 8 hours of sleep total, but wake up in the middle to go to the bathroom and reddit for several minutes, is it as effective as getting 8 uninterrupted hours of sleep?
[ "It depends when you get up. You go through cycles every 3hours (ish). The first half isn't the important one, the last half is - it's the part where (current theory is) your brain cleans out waste. Which is why a nap can give a short term mood boost, but doesn't have the same effect as 3 or 6 hours of sleep, becau...
[ "You get used to it. Technically you can be fully functional with 2 hours of sleep a day. Look up polyphasic sleep and Buckminster Fuller who reportedly took 4 thirty minute naps a day for two years. Anyway, it really sucks when you start, but you can adjust your sleep schedule to require less hours, basically by g...

What would happen to a deep sea fish that is used to thousands of pounds of pressure that was brought to the surface.
[ "It dies. Deep sea creatures sort of explode when brought up from the depths. Not an awesome action movie explosion but their organs leak and they just sort of die. It's like when your ears pop in an airplane but 100x worse." ]
[ "The pressure is \"crushing\" for us because our bodies contain air. We have air in our lungs, air in our eardrums, and air in the submersibles we put in the water. This creates an enormous pressure differential. Sea creatures don't have any air in their bodies, the pressure difference between 20ft in depth and 20,...
