While the McFly hoverboard turned out to be a very elaborate hoax, some dudes from France made it happen for real, using hoses, pumps, and a control interface. It's called the Hoverboard by ZR, and it uses the same technology behind the Flyboard, which you know better as the crazy-water-ironman-suit-jetpack-thing-with-the-hose. Controlling this awesomeness is a handheld throttle that gives the rider total control over the hose's power, and whatever God-given balance skills you're blessed with.
This Sport Takes Ice Skating to Extreme Heights
Since the engorged hose takes on an extremely stiff nature, you can get this to do incredible things—let's agree that it lives up to its name. If you're already lucky enough to have a Flyboard, you can purchase the board-only version and have options. The total cost of this system is around $6,000, but that doesn't include the powerful jet ski you need to pump water through the 59-foot hose; those can often go for upwards of $10,000.
