OK, so it only gets 3 or 4 inches off the ground (less for the heavier gent), and you'll need plenty of liquid nitrogen on hand to keep the internal magnets cool. And before any hovering fun can be had you'll need to make sure the surface you plan to do it on also has the appropriate magnets installed.
Still, progess innit.
The day when we can all properly Marty McFly is edging closer, slowly.
