Jet skiing isn’t as exciting as it used to be? Maybe Jetovator is more your speed. Essentially a flying stunt bike, Jetovator’s water propulsion system allows the rider to float up to 25 feet in the air or take underwater dives, all while trailing a 40 foot fire hose rigged to an existing personal water craft (thrust is redirected). Currently, the rider must be accompanied by a jet ski operator to hold down the throttle (duct tape won’t work too well during takeoff and landing), though a fly-by-wire model for independent riding is in development. Regardless, at less than one tenth the cost of a JetLev, we’ll go with the Jetovator.
