When was the Second Amendment limited to firearms (as opposed to explosives)? | [
"Explosives were explicitly restricted in the 1934 National Firearms Act, where most explosives and any non-shotgun with a bore larger than 0.5\" became regulated as [destructive devices](_URL_0_). There are strict regulations on the manufacture and transfer (sale) of anything classified as a destructive device."

"If the Congress of the United States tried to pass a law unreasonably restricting your right to keep and bear a sword, that law would be challenged on the same grounds as a law unreasonably restricting your right to keep and bear a gun. \"Arms\" means arms. It doesn't mean *fire*arms specifically."

Why is there not the same Soccer hooliganism surrounding North American Sports? | [
"For all the reputation the U.S. has as a bunch of crazy gun-toting rednecks, we have a very strong tradition of a certain level of civility. My students (who are studying abroad here from their home countries around the world) frequently comment on how sane and relatively civil our political behaviors (as opposed ... | [

Why does water on the ground and outside evaporate even if the temperature never reaches 100 degrees Celsius? | [
"Because water begins to evaporate before it reaches boiling point, some the water molecules speed up enough and break from their bonds with the body of liquid. Water can evaporate at room temperature, just much slower due to less energy."
] | [
"No, water does get somewhat denser if it is frozen at colder temperatures. Additionally many plants have chemicals and enzymes in them that lowers the freezing point of the water in their cells. So the water in them might not freeze until the temperature is 10, 0, or as you state -20."

Why does being worried about laughing make it hard not to laugh? | [
"Seems like the reasoning could be rooted in the \"White Bear\" problem or something called [ironic process theory](_URL_0_). Trying not to think of something causes you to think of it more. Basically, part of your brain avoids thinking about whatever it is (laughing, white bears, whatever) by thinking of things th... | [

How did Germany recover their economy and become an economic powerhouse, after losing 2 world wars, paying millions of Euros of reparations and being annexed by 4 nations? | [
"1. Most of the reparations for WWI were forgiven after WWII. 2. A lot of money was pumped into Germany after WWII to rebuild it because the US didn't want them to fall to communism. 3. Germany has always been one of the major economies in Europe, so it is really a reversion to the mean. 4. Annexed by 4 nations? It... | [
"Partly because Japan was already going in that direction before the war. In the mid 19th Century, US gunboats showed Japan how backward they were, which lead to a massive modernization and westernization movement. One of the things other world powers had that Japan did not were colonies, so Japan made some out of ... | eli5_question_answer | {

How do people like George Zimmerman and Casey Anthony stay safe? | [
"Jack Ruby asked for protection from the Warren Commission after he shot Lee Harvey Oswald as he believed his life was in danger, but he was declined (partly due to the public interest in the case, and because the Warren Commission had no police powers to protect him).

How do cities with high annual rainfall deal with construction? | [
"Concrete doesn't 'dry', it 'cures'. When it hardens, it's because of a chemical reaction that works just as well underwater. So rain is no problem."

How can movies like 'The Possesion' about a moth demon growing inside a child claim to be 'based on a true story'? | [
"a) It could be VERY loosely based, but still be 'based on'. This is a marketing gimmick. b) It's based on one specific version of the story. See \"The Exorcism of Emily Rose\". She has a condition where her body locks up in very odd, somewhat terrifying poses. The doctors say it's one thing, the priest says it's t... | [
"The more I have to suspend my disbelief, the more difficult it is to be scared. Consequently, Freddy Krueger and Jason don't terrify me at all.
