My fantasy. Your fantasy. Marty McFly's 2015 reality from Back to the Future Part II. The hoverboard now exists, for real, thanks to the magic of superconducting magnets, quantum levitation, and the boundless brilliance and ingenuity of the French.
This hoverboard, called the MagSurf, was built by the coolest teacher ever at Universite Paris Diderot in France. It works on the same basic principles as that little levitating puck from last week, where an array of powerful supercooled magnets create an electromagnetic field that's stable enough to keep them (and whatever they're attached to) in a hover. The difference is, MagSurf is big enough that YOU CAN FREAKIN' RIDE ON IT.
See it for yourself in the video right here:
Yes, the current Mk.I MagSurf hoverboard does only function when placed on a magnetic track, but I'm sure there's probably an easy way around that.* And as a bonus, it's also a smoke machine at the same time. In other words, it's the perfect accessory for your next '80s theme party, just for heaven's sake don't get drunk and try to ride it over a swimming pool.
