Remember those cartoons where some poor character would open up a fire hose, only to be flung about from its power like a rag doll? The JetLev Flyer harnesses the power of high pressure water into a jetpack, enabling you to fly 10m above a body of water. A hose attached to a motor pump unit supplies a constant stream of water while simultaneously stopping you from flying off into oblivion – a handy feature, we think you'll agree.
