Bowling ball hanging by a chain from the catwalk.

Suspend the bowling ball from the hook on the catwalk. Sit on a chair at a location such that, when the bowling ball is displaced from equilibrium to the height of your head, it is touching your face. Release the bowling ball to swing across the room. Hold your head very still so that the ball comes back and almost collides with your face.
