There is technically a "hoverboard" in the sense that it can hover but it only moves on a specific trail that has to be set up due to it using magnets n **** . Also, apparently a kid stuck his hand under the hoverboard or something and froze his hand and tried suing. Its still prototype and I never cared about looking into this supposed lawsuit. Also, the hoverboard uses liquid nitrogen, hence a kids hand freezing being a plausible thing.
Burst my bubble? This is what I've been waiting for. Ever since I watched Back to the Future 2, I knew that they would have a vagina selfie stick for Facebook.
If we're talking about the one in the car advertisement, it wasn't exactly fake, if I remember- it was more that the board was following a specific course and the skater didn't actually have control. It still hovered.
