Check out this working hoverboard!
Superconductors made of yttrium barium copper oxide are inlaid into the body of the board. Placed into two reservoirs within, this compound is cooled down to below a chilly –181oC (–294oF) in liquid nitrogen, which is the mysterious gas emanating out of the hoverboard. Once cooled, the superconductors store a magnetic field, generated from the 200 meters of magnetic track built into the skatepark. And so the hoverboard hovers.
