We reported before about the Lexus Hoverboard and showed couple of teasers that were published on YouTube showing this cool thing Hovering on air.

Is it Real ? YES... Lexus has officially unveiled its Hoverboard in Spain. It's sadly not as cool as we expected. firstly, It can't be used anywhere you want... it needs a special "Track" in the ground like the train.

In the video ads, Lexus build a special Park for it, The park is made out of wood that has been painted to look like cement, with an embedded magnetic track that had clearly been covered with some sort of plaster in an effort to conceal it. Strike one: the Lexus board can't be used anywhere you want. Marty McFly would be disappointed.

One more let-down, Lexus hoverboard works with liquid nitrogen-cooled superconductors and magnets, which means it needs to be cooled down to around -180 degrees Celsius using liquid nitrogen in order to achieve levitation. so you gonna need a fresh supply of liquid nitrogen with you all the time. You can watch the full story in the video below.
