It was annoying that the article said:
But when the 190-pound visitor stood atop the 100-pound board, one gentle push was enough to send him spinning across the room over a cushion of air.
This is very poor writing since there is no "cushion of air" involved, the air is not supporting the weight of the board and rider, it's a magnetic system after all. It would probably work almost exactly the same in vacuum.

- marknutter 12y agoWell, he is technically right. There is air underneath it, and it could be described as a cushion, albeit a poor one. Remember he's trying to explain it in terms that non-technical people will understand.
