These guys are transforming childhood dreams into realities. The hover-board was first put on the map by Marty McFly, in Back to the Future, and has recently been brought back to light via l’université Paris Diderot-Paris7. Very awesome.

Mag Surf is a demonstration of superconductor magnetic levitation. The board, which vaguely resembles a skateboard, rides on a magnetic track. Super-cold liquid nitrogen turns a special metal material on the bottom of the board into a superconductor, which powerfully repels the magnetic field in the track and pins the board to the edge of the field. The effect is like an invisible rail.

The demonstration was put on by the Universite Paris Diderot at its science fair last week. Mag Surf was built by researchers in the university’s Materials and Quantum Phenomena Laboratory.

Despite the requirement for a track and the rigid relationship between the track and the board, there’s potential for more interesting rides than the one in the video. The key is building the right track. Check out this viral video of a similar superconductor levitation project by researchers in Israel. Now imagine a magnetic track modeled after roller coasters and you begin to see the potential.
