Powered by AIR and hours of fun! No batteries are needed for the which means it's always ready to go. The Whirlwind Air Rocket comes fully assembled and the launch base will take just a few minutes to set up! Standing almost a foot tall, pumped up and ready to go, the Whirlwind can climb to 150 feet and "whirl" back to earth! The rocket's foam nose cone creates a "bounce" for quick and easy recovery and it's ready to launch again!
