This is a replica of Marty McFly's Hover Board from Back to the Future 2.
It is made from wood that was covered with a thin sheet of styrene which
I painted using spray cans, because I did not own an airbrush at that time (1992).
The magnet assembly on the bottom of the Mattel Board was made from sheet styrene.
