After crushing the hearts of "Back to the Future II" fans everywhere earlier this year with his too-good-to-be-true hoverboard announcement, Tony Hawk is making it up to us with a demo of some actual levitation technology.
The pro skateboarder recently tried out the Hendo Hover, a $10,000 prototype hoverboard that's currently in the proof-of-concept stage. According to inventor Greg Henderson, the technology relies upon magnetic fields to achieve levitation (about 1''), meaning it currently won't work over anything but non-ferrous materials like aluminum or copper.
