You will not believe your eyes, but what you are seeing is true. These balls will actually be bouncing higher in the air than the height at which you drop them. With this kit, you will be able to do something that is almost impossible with any other kind of ball. By harnessing the power of super-elasticity, and learning about the physics behind collisions and acceleration, you can make your own rocket balls. How high can you launch them into the sky?

This kit includes everything that you need to repeat the experiment several times. With four different sized molds, the amount of times it can be recreated will vary based on which size you choose. It also comes complete with a pair of safety goggles, and a fully illustrated and colored instruction booklet.
