Pranksters played a 'invisible rope' trick and caused a two car crash.
In a video shared online, two youths stand either side of a road, that appears to be the entrance to a car park or residential parking.
As cars approach, they clench their fists in front of them and lean back, as if both pulling on a rope.
The action causes drivers to think there is a rope in front of them, and they slam on their brakes to avoid hitting it, pulling the boys down.
The filmer realises they have caused a huge problem and all three of them start to run.
The driver of the first car gets out and chases them, screaming at them in fury.
It's not clear where in Britain this was filmed, but it has provoked strong reaction.
Some are convinced the video is fake, and one commenter said the prank never fooled anyone when he was younger.
