The future is now.

Hoverboards finally exist. And if you have $10K lying around, you can have your very own, just like Marty McFly. Or at least you can soon. The first 10 production hoverboards have already been snatched up by Kickstarter backers who shelled out the hefty pledge.

Invented by California-based company Arx Pax, the current prototype of the hoverboard called the Hendo will hover about 3cm off the ground for about 15 minutes while carrying the weight of about two average people, according to The Guardian.

But it’ll only float on certain surfaces—namely made of non-ferrous metals like aluminum or copper—because it uses magnets to float. So you aren’t going to be able to fly it around the town square like McFly (played, of course, by original gangster Michael J. Fox) did in 1989’s “Back to The Future II.”

Arx Pax is looking to snag $250,000 in funding via Kickstarter to go from prototype to production.

“It is still early days, but wea re absolutely thrilled because we have proven conclusively that what was widely considered impossible is, in fact, possible,” says company founder Greg Henderson.
