Big step for quantum teleportation

If you're wondering how it's even possible to shoot a gun underwater, gunpowder contains oxygen — a key element in the firing process — the gun still goes off exactly as it would on land. Water is 800 times denser than air, so unlike a bullet fired above the surface, once the bullet hits the water it immediately begins slowing down.
