Slap it with your hand. Slam it on the ground. Either method powers the foam rockets into the air with blazing speed…up to 50 feet high! A member of Geospace's popular Pump Rocket family, the Slap Rocket has a unique launching system that kids find endlessly entertaining. They simply load one of three included soft, safe foam rockets onto the launcher, grasp it firmly, and use their other hand to either push or slap the soft plastic “bellows” plunger at the base. For even longer flights, slam the plunger onto any firm surface. Includes launcher and 3 foam rockets. Additional replacement rockets especially for the Slap Rocket are also available (sold separately).
