Lexus has created a real, rideable hoverboard

There are soft wisps of vapour that can be seen during that clip.

My money is on it being a compact cryogenic superconductor and the Meissner effect.

A new state of the art in compact cryogenics would be pretty cool. (pun intended) But this hoverboard is likely little more than a gimmick.

Good analysis! I'm just hoping that it is real and one day I can get on one. Its a step in the right direction though.
