The award winning Air Burst Rockets System 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 s from a stand-up bicycle , its rockets can be easily and repeatedly launched. And the system is completely safe -- no combustible or expensive rocket engines used! With five different altitude levels to choose from, you can launch Air Burst rockets to varying heights reaching up to 1,000 feet and even beyond visual range.
