I was watching a video on where this guy spins a a dial or capsule or a cap (I couldn't really tell, but it was like a long thing cylinder capsule look a like) and well he gave it a quick push and the cap came to a stop and than reverses direction.
What could cause this?
I know that angular momentum is not conserved because of external torque (gravity) and friction causes the thing to come to a halt, but why would it reverse direction. Where does it get the force to reverse direction?
