Why Does The Bullet Spin In Place When Shot On Ice?

When you shoot a bullet at ice, something interesting happens—it gets stuck and keeps spinning. You see, as a bullet travels through the gun, it's surrounded by these spiral grooves which forces the bullet to spin rapidly as it exits the barrel. This spinning motion helps the bullet fly straighter. If you shoot at ice, the ice holds the bullet in place, and since ice can be slippery, the bullet will keep spinning for a while before stopping completely.
