Astro Blaster

Description:

Four rubber balls of decreasing size are threaded on a common rod. The balls are free to slide on the rod, but only the top (smallest) ball is free to come off the rod. If the stack of balls is dropped on the floor, most of the momentum and energy of the three lower balls is transferred into the top ball during the collision with the floor. The top ball flies off the stick to a much greater height than the drop height.

Procedure or Operation Notes:

Hold vertically away from your body and drop. Safety glasses are recommended and available.
