It's pretty impossible to shoot a gun effectively underwater. Not because guns can't fire underwater -- they can, actually. So what's the deal?

The problem is the water itself. Water is 800 times denser than air -- which makes it 800 times harder for a bullet to meet its target. One scientist decided that instead of just ~sharing that fact~ with all of us, he would put himself in mortal danger for science.

Physicist Andreas Wahl is host of a show in Norway called "Life on the Line," and in every episode he puts himself in a potentially fatal situation to prove a point (like when he leapt off a building to show that a rope could make a knot because of his falling body weight). #SMH

For this experiment, Wahl stands in front of a semi-automatic gun in a pool to show that the bullet fired at his (very much not invincible) body would never make it there -- and it doesn't, but still.

Because there are always *those people* who see a dangerous thing on the internet and want to try it out immediately, we'll just say now ? Do ? Not ? Shoot ? Bullets ? At ? Your ? Own ? Body ? For ? Science. Leave that to Wahl and all other brave-as-hell physicists.
