Back To The Future Part II
In Back To The Future Part II, teenager Marty McFly (Michael J. Fox) is rocketed from 1985 to the year 2015, which, as predicted by screenwriter Bob Gale, features robot-served petrol stations and automatic dog-walkers. It also boasts fax machines attached to post boxes – perhaps a bit less practical than sending an email.

But the new technology that really left teens who saw the movie in 1989 jealous were the cool hoverboards. Essentially skateboards without wheels, they floated a few centimeters off the ground and featured heavily in the movie’s chase scenes. And everybody wanted one.
Sadly, even now practical hoverboards are a distant dream. There have been some attempts to build a real one. But the designs have often been based on electromagnets, and only work on special metal surfaces.
So, for now, we’ll all have to make do with skateboards!
