Demo 03-11 High Bounce Paradox

Normally a ball can only bounce up to a maximum height equal to the height from which it was dropped, and this can only occur in the virtually non-existent case of a perfectly dropped ball. This demonstration shows the case of an object that "bounces" higher than it started originally.One half of a handball is flipped inside out and dropped onto the floor. The mechanical potential energy stored in the ball when it was distorted is released as the ball hits the floor. This energy is converted to kinetic energy of the ball, increasing its upward speed after the collision with the floor and causing the ball to bounce higher than the position from which it was dropped
