Jump it UP! Thump it UP! WAY UP! How far? How about the height of a 20-story building! Simply slide the safe, foam Jump Rocket onto its launching pad, jump up and land on the hemisphere-shaped air pump, and watch it BLAST OFF… to a height of up to 300 feet! It couldn’t be easier, simpler or more FUN. Kids even get some exercise, too, every time they jump on the pump. We’ve improved the technology with our Thrust Booster, doubling the flight distance of previous versions. For junior astronauts and parents who want to amaze all the neighbors. Includes air pump, launch pad and 3 soft foam rockets. Ages 6 and up.
