Description: - Smaller disk at the top provides a flat surface to place the water balloon - A spring connects large disk to the bottom of the cylinder - A clamp with a second spring moves vertically, providing the mechanism to depress the large disk - Cylinder measures 5 ft in height - The clamp measures 1 ft in length How it works: Human force will push down the clamp, depressing the springs attached and storing mechanical energy. The clamp will press the disks, which will compress the spring located in the center of the cylinder. When released, the mechanical energy stored in the springs unleashes stored energy and will cause the water balloon to launch, higher if more human force is exerted.
