Abstract
An improved amusement device includes a base and open-top guide tube with two or more balls in the tube. When the balls are lifted to the top of the guide tube and dropped, the top ball rebounds to a height much higher than that from which it was dropped. With three balls in the tube, for example, the top one will typically rebound to a height six times as high as the height from which it was dropped.
