Who knew scientists were so wild?
Norwegian physicist Andreas Wahl, as part of a series about proving real science via life-threatening situations, already dangled from a building to prove a point and now he's upped the ante by aiming a gun at himself under water and pulling the trigger.
Of course he was unharmed, thanks to the resistance of water being greater than air (SCIENCE!) but you have to admit it's still pant-wettingly scary to do. Luckily he was the only one in the pool.
