JetLev Flyer

At first glance we thought the JetLev Flyer was just another crazy concept gadget. But no, it's actually real - a personal flying machine that runs on a complicated water pressure system.

The JetLev Flyer is the result of nine years of development, and it's a dream come true for anyone who's ever wanted to act out Super Mario Sunshine, or zip around a marina in a manner that would make James Bond jealous.

Running on a four-stroke engine, this amazing machine lets you hover 1 -feet above the water; the top speed is around 30mph. Users can even dive beneath the sea in short bursts, before leaping skyward again like a strange human/dolphin hybrid.
