One spectator holds a rubber ball while another spectator holds a piece of modeling clay. The magician removes the "bounce" form the rubber ball and places it into the modeling clay. The spectators end up with a rubber ball that doesn't bounce and a piece of bouncing modeling clay. You finish clean and everything may be examined.
