While we’re still a long way off from achieving the kind of technology that allowed Marty McFly to effortlessly skateboard feet above the ground, the Water Hoverboard is very much a real thing. Essentially a wakeboard with a high-powered water jet at its rear, this hoverboard attaches to your personal watercraft (think jet ski) with a long hose, propelling you up to 16 feet above the water, at speeds of up to 16 miles per hour. Once you’re set up, you can perform wild aerial tricks like flips, spins, summersaults, and more — or just rip across the water like some insane dolphin-human-robot hybrid.
