Hoverboard
You can call hoverboard “floating Skateboard”. The name comes from the science fiction comedy Back to the Future II from 1989.
You can’t officialy buy a hoverboard today. Lexus Hoverboard SLIDE model (from the picture) is only a prototype. It weighs 11.5 kg with all magnets and liquid nitrogen. It has magnets in it, because they are working with a magnetic Background.
It’s only a matter of time before we get Hoverboards.
