Flyboard, A Water Powered Jet Pack
Flyboard is an amphibious water-powered jet pack that propels the wearer up to 30 feet in the air (demo video). A large hose channels high pressure water to the Flyboard from a nearby jet ski. Two large jets at the wearer’s feet provide the propulsion, with two smaller handheld jets providing control. Flyboard was designed by French jet ski racer Franky Zapata of Zapata Racing.
