A levitating hoverboard which runs on a specially constructed skate park has been unveiled by car manufacturer Lexus.
Footage released by the firm showed skateboarders testing the hoverboard with varying degrees of success.
The film was recorded on a specially constructed skate park near Barcelona in Spain.
The hoverboard contains powerful magnets which are cooled to -197 degrees celsius with liquid nitrogen, allowing the board to ride along a track hidden in the surface of the skate park.
The firm said the hoverboard was a prototype and would not be available for sale. The skate park has now been dismantled again.
