Mythbusters, guns, and H2O
Jul. 14th, 2005 11:31 amToday's Mythbusters tested a myth in which if you're under water, you can be protected from firing bullets. While unconfirmed for 9mm (10+ feet, we really need to firmly test this), shooting 233's, M-1's, and 50mm into water is confirmed at over 5 linear feet -- they distentigrate when they hit the water over a distance over three linear feet.
Linear feet, aka distance from the target to the gun. Not how deep you're in.
Why did they disentigrate? Well, you're shooting bigger bullets faster, which will have more resistance when they hit the water (which is roughtly still). Equal and opposite force pushing back, which means they could be hitting the theoretical slice of lemon wrapped around a gold brick, which was piled up against a thick wall of steel and concrete. The 9mm, the bullets are fast but they're light enough so that they can't disentigrate, they just go straight in.
I really want to see what distance of water that 9mm needs to traverse before water friction gets the better of it.
