The Air Burst Rocket incorporates an entirely new propulsion technology utilizing air to create a shock wave 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 model rockets to amazing heights. With a few pumps from a stand-up bike pump (pump not included), its rockets can be repeatedly and easily launched. No combustible or expensive rocket engines are used. With five different thrust levels to choose from, you can launch Air Burst rockets to varying altitudes reaching over 1000 feet beyond visual range.
