I was going to pass on posting about the re-rerelease of the Back to the Future Hoverboard replicas from Mattel until I watched a little bit of another Hoverboard video featuring Bob Gale, the co-creator of Back to the Future. He’s talking about items featured in an auctioned that benefitted the Michael J. Fox Foundation for parkinson’s research. Blah, blah, blah until you get to the part about one of the original props being auctioned at Sothebys for $17,000, and then being resold a few years later for $55k. (!) Also interesting, the mechanical effect used to make the hoverboard appear to float when thrown on the ground. The video shows two different boards, one used for the wire flights and one used for the throw down.
