With such nerd topics as how to extinguish the sun with a big water gun:

For those that say “but space has no oxygen so combustion can’t happen!”

As the video states: Modern ammunition contains its own oxidizer so firing in space wouldn’t be a problem

An interesting talk that is definitely worth watching:

Every time I see one of these types of scientific videos where they talk about wounds, I realize how bad I never want to be shot.

The rifle v.s. handgun pictures he shows are especially frightening.

LOL at the zombie target joke at around 13:12.

Summary:

  • Handguns are not as deadly as most people think.  6 out of 7 people survive their injuries
  • It’s impossible to assess injury severity at scene properly
  • There are often no exit wounds
  • Handguns have a very low penetration depth
  • Be concerned about airways
  • The most likely death is due to hemorrhage
  • Quick transport to OR is key

Moral of the story is that if you’re going to get shot you better hope it’s with a handgun.  On the flip side of that Clint Smith’s saying  “The only purpose for a pistol is to fight your way back to the rifle you should have never laid down.” definitely holds true, because you’re going to want a rifle (if you have the option) to stop the threat.

Using a modified version of Newton’s cradle, a series of stainless steel balls suspended by fishing wire, scientists from the California Institute of Technology have created a powerful weapon for soldiers and doctors known as a “sound bullet.”

Full Story – HERE

Luckily the article goes onto say that metamaterials ( which is what they refer to this field of science as ) are very difficult and time consuming to create.  Hopefully the TSA doesn’t blow this out of proportion or we will all be flying naked soon with gags in our mouths over fear of acoustic terrorism.

It will be interesting to see what new inventions and applications come out of this.

Wait until some genius thinks he can be Kenny G by putting a loaded AR-15 up to his mouth and blowing.

Speaking of Kenny G, that dude plays a mean horn… not to mention he has some killer hair :P
