High Bounce Paradox ("Dropper Popper") (1M40.91)

Description:

Similar to a raquetball that has been cut in half. Invert the curve of the ball with your hand. When dropped, the ball will pop back upon colliding with the floor, releasing the stored energy you put in and making it bounce higher than the release height.

Procedure or Operation Notes:

Be sure to drop it from a sufficient height (approximately 1 foot) that will cause it to revert and spring to above the release height.
