00:00The bullet spins fast as it's shot out of the barrel, and if it hits a frozen lake,
00:05the hard icy surface stops it almost immediately. But the impact creates heat,
00:10melting a tiny thin layer of water beneath the bullet. This makes the ice super slippery,
00:16with almost no friction. And if it lands upright, that spin helps it stay balanced.
00:21So instead of tipping over, the bullet can actually stand up.
