In the 1989 classic Back to the Future II, skateboarding teen Marty McFly and nutty scientist Dr. Emmett Brown travel to the future, a heady place where kids zoom about on hoverboards, flying cars are powered by household garbage and shoes tie themselves.

Without question, Marty’s Mattel Hoverboard is the most recognized and revered prop from Back to the Future II. These hoverboards worked similarly in principle to skateboards in that they needed momentum by the rider and most would become useless in terrain not suited for them, for example, water, unless you have the more powerful Pit Bull model.

Data: “Hey McFly, you bojo! Those boards don’t work on water!”
Whitey: “Unless you got power! Hahahah…”
