Amazon.comKids can get rid of some excess energy with this air-powered outdoor rocket toy. No battery or fuel is needed to get the rockets airborne--just some old-fashioned stomping power. Set up the simple launch stand in a clear outdoor area, connect the 38-inch-long vinyl air hose and blast pad, load one of the 9-inch yellow foam rockets--and watch out. Our 5-year-old assistant reviewer really got a kick out of jumping on the purple blast-off pad and watching her rockets soar 50 feet or more, though she had to fight the adults for a turn. If the three rockets included with the kit aren't enough fun, you can order stomp parachutes and spin copters from the manufacturer. --Marianne PainterProduct DescriptionThe original Stomp Rocket Jr. Glow is 100% KID powered!
