Bullets fired into ice bounce, and spin like crazy
Friday, October 15, 2010


So what is going on here? Well the bullets are bouncing out of the ice every few shots, into the air, and landing again on the ice. That is actually the most remarkable part of this video, but these guys do not seem shocked. That the bullets spin and spin for a long time is not very shocking. Firstly, bullets from a rifled gun routinely exceed 3000 RPS. That is 180,000 RPM. Very very fast for an object as massive as they are. Ice is also almost frictionless to a hot object. There are some scenarios where bullets can break 500,000 rpm. That is a ton of angular momentum.

I am personally interested to see that the bullets are not deformed in any way by the impact.
