No one should ever have to face the other end of a gun barrel but if you manage to find yourself in such a situation, let’s all hope that it’s underwater. Here’s our favorite physicist Andreas Wahl proving how the velocity of a bullet slows down like crazy when it’s fired underwater with a lovely visual experiment. The bullet totally nosedives after getting shot and only travels a few feet. If you’re more than like 5 feet away from the rifle, you’d be fine.
I’d still want to be at least 5 miles away from the end of a gun, though.
