The only catch is that, unlike Marty McFly’s board, Hendo’s levitation trick only works when the board is sitting atop a non-ferromagnetic conductor — in other words, a solid sheet of metal that doesn’t contain iron or steel.

Ever since Marty McFly took to the air in the 1989 classic Back to the Future II, humanity has been eagerly awaiting the arrival of a real, fully-functional hoverboard. Since then, tinkerers and scientists the world over have launched countless attempts at building such a device, and now, after more than 25 years of trying, technology has finally caught up with our far-fetched dreams. Thanks to a startup by the name of Hendo Hover, the hoverboard is finally a real thing that exists in the world that you and I inhabit.

How is such a thing possible? Well, according to the company’s Kickstater page, the magic behind the Hendo Hoverboard lies in its four disc-shaped hover engines. These are essentially giant downward-facing electromagnets that work together to create a powerful magnetic field which literally pushes against itself, thereby generating the lift which levitates the board above the ground.
