Spinning bullets... on ice?

[RogueSnake79]

Weird if true, I guess I can test it out on my refrigerator.

The bullet seemed in very good condition after hitting the ice. Not deformed at all...

If the ice stopped it mechanically, the thermal energy extant in the bullet might cause it to caper as seen in the video.

You can do something not too different with pennies in blocks of dry-ice (frozen CO2). Stick them in more-or-less vertically, and the heat inherent to the penny will cause it to flip back and forth.

The heat inherent to a bullet stopped in a similar manner might cause the 'dancing' seen in the video, remembering that the bullet is subject to the same thermomechanical stresses and forces as the aforementioned penny, and is circular with respect to said forces where the penny is planar.

Hey, he's not A.K.A. Mr. Awesome for nothing!
