Powered by AIR and hours of fun! No batteries are needed for the Sonic Booom which means it’s always ready to go. The Sonic Booom 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 Sonic Booom can climb to 150 feet! The rocket’s foam nose cone creates a “bounce” for quick and easy recovery and it’s ready to launch again!
