Wow! Now kids as young as 3 years old have their own "Junior" JUMP ROCKET® model thats all their own. The JUMP ROCKET MINI is a scaled down size of Geospace's best-selling Jump Rocket for younger children! Like the full-sized version, it features an air-powered launching pad connected by a hose to the rubber pump. When young spaceship commanders place a rocket on the pad, take a big leap, and land on the pump, air pressure causes the rocket to explode upwards up to 75 feet high!
