Kickass scientists tease hoverboard dream using lasers to move magnets

You've already seen Doc's fancy electronic petition come to life with the iPad, as well as the McFlys' virtual telephones via Skype and FaceTime. But, though a dude did build a real-life hoverboard, it could only take up to 5 pounds, leaving our universally drooled-over "Back to the Future Part Two" skateboard a mere fantasy. But it's one that looks a step closer to reality in this viral video, which shows Aoyama Gakuin University researchers moving magnets with light. They use the lasers to change the temperature of the graphite in the discs, modifying how they interact with its magnetic field and creating movement — in other words, possible early hoverboard technology. Cue the "Power of Love" montage! [Source]
