So how does the hoverboard even work? Hoverboards have been faked before, but what Lexus is doing isn't exactly a lie or a hoax. They made a real, working hoverboard, and that's what's on display here. It's just an incomplete truth. Lexus also made a skatepark with magnetic rails buried underneath, which makes the whole thing possible. The mechanism is based on the concept that when magnets have opposite poles, they repel each other and force a space between them.
