The award winning Air Burst Rocketry incorporates an entirely new propulsion technology utilizing air to create a shock wave and venturi effect that launches its rockets higher and faster than any non-combustion rockets on earth! Through the bursting of membrane boosters within the launcher, AIR BURST generates astounding power that sends its rockets to amazing heights. With a few pumps from a stand-up bike pump, its rockets can be easily and repeatedly launched. No combustible or expensive rocket engines are used. With five different altitude levels to choose from, you can launch AIR BURST rockets to varying altitudes reaching up to 1,000 feet and even beyond visual range! Be prepared for a truly amazing model rocketry experience
