Standard Pump Rockets are a rollicking blast to fire. But our new Bungee Blast Jr ramps up the fun and excitement by an order of magnitude. We've engineered a patented elastic bungee cord inside the pump cylinder to turbo boost the launching power. Load a foam rocket into one end and pull back the cylinder, feeling the increasing tension of the cord inside. Then let go. Kids will be amazed as the stored energy of the cord pushes the piston of air very forceful, blasting the rocket out at hyper-speed. It's like putting a turbo-charger inside! Ages 3 & up.
