Not a prank as much as a stunt, but still great fun. Once this video gets out, a whole industry will probably prop up creating pallet-sized skateboards to run on the trolley tracks to make it faster to get around town.
Until someone passes a law saying you can’t do that.
Here’s more from the YouTube description:
In Back to the Future, Marty McFly showed ingenuity when he cracked apart a kid’s 1955 wooden push-scooter to “invent” the skateboard. Now, Czech artist Tomáš Moravec is keeping McFly’s low-tech, high-fun tradition rolling with his Pallet Skate. Moravec cut down the dimensions of a standard, European wood pallet, or “Eur Pallet,” and fastened what appear to be small cart wheels to the bottom, creating a giant—and specialized—skateboard. The Pallet Skate fits snugly into the tram tracks running through Bratislava, the capital of Slovakia, and with a few pushes, Moravec glides smoothly around the city.
