Last month, Arx Pax showed off a real, working, honest-to-goodness hoverboard. The thing was, no one could really ride the hoverboard the way you would want them to.
Enter pro-skater, king of all boards Tony Hawk, who, while managing to do a couple of shove-its, also can't really ride the hoverboard. (At least not a real one.) He can spin endlessly until he falls over, he also did the first ever bert, but that's about it for this prototype hoverboard.
You can read all about his antics over on Ride.
