The AstroBlaster is the one-of-a-kind Multiple Collision Accelerator that fits in your pocket! Put the red ball over the tip of the AstroBlaster, hold the tip and release so that the AstroBlaster falls straight down. When the AstroBlaster hits a hard surface, it creates a shock wave which propels the red ball over five times the drop height! Works on the same physical principle as witnessed during the creation of a supernova. So cool, it comes with its own safety gear! Ages 8 and up.
