HydroBlast Cannon has three parts water tank, balloon storage and launcher tube. The water tank is made up of stainless steel to avoid corrosion. We can use the attached rope to pull the Cannon to play area. Pick the balloon from storage, fill water from tank and place it inside launcher tube. The tube is made of glass. The balloon rests on a steel launchpad with soft cushion. This launchpad has a handle on another end. In between the two, the spring rests inside the tube. Now, pull the handle using human strength so the coil will get compressed, creating potential energy. After releasing the lever, the coil will transmit the potential energy to the balloon as kinetic energy. And with this energy, the balloon will launch in a splash! Cannon is kids-friendly with size as 8 ft x 4 ft x 4 ft.
