Astro Blaster

The Astro Blaster demonstrates Newtons laws of conservation of energy and momentum in an amazing sort of way. There are 4 balls which are held in alignment by a plastic rod. When the unit is dropped and the largest ball on the bottom hits the floor, the top ball will shoot off at amazing speeds. The top Astro Blaster ball can reach heights of over 5 times the height of the initial drop height! Its a real surprise as you just dont expect that top ball to shoot off that high!
