Extra Bounce

It looks like the instructions are inaccessible, but you bounce a ball like a tennis ball or a kickball, then a ping pong ball and note the differences in the height of the bounce. Then put the ping pong ball on top of the bigger ball and let them go together and the smaller ball will go flying up or out because it is energized by the bounce of the bigger ball.
