[QUOTE="Keyser328, post: 1322223, member: 10111"] I don't know if it's legit or not. I brought it up full screen and saw that the bullet hit, bounced, then landed spinning. As far as [I]why[/I] it was still spinning is easy. The rotational velocity was maintained on impact with the ice. At that speed, the surface of the ice will actually melt, creating a very low friction surface and not impede rotation. Why it stands on end is fairly easy too, its the same effect that causes a top to spin and stay up, even when its center of gravity is higher than the surface. The part I can't figure out is why the bullet doesn't deform. The only vaguely plausible idea is what I mentioned with the ice melting a micro layer of water and between that and the ice itself, lengthening the impulse of the impact enough to not deform the copper. Ice is some weird stuff and something "bouncing" off ice doesn't strike me as impossible. The bullet bounces up from the hit, but is still spinning fast enough to land and stand up like a top. I really hope MB tests this, because I'm anxious to see it. [/QUOTE]
