This guy really, really wanted to prove a point.

To demonstrate the difference between air and water resistance, Norwegian physicist Andreas Wahl decided to stand in front of a submerged rifle and pull the trigger.

As he expected, the bullet drifted harmlessly to the bottom of the pool without touching him.

But no matter how confident he was in the science behind what he was doing, you have to admit that pulling that trigger would have been an absolutely terrifying experience — and the relief on his face after the bullet falls short of its target says it all.

This should go without saying, but guys, no matter how much you love this video, DO NOT TRY IT AT HOME.
