English plumber, garage inventor and YouTuber Colin Furze has built an actual working hoverbike - an "unhinged flying bike/human blender [that] unbelievably gets off the ground and actually FLIES," as Furze puts it.
Furze's YouTube video, which shows his attempt at flying the bike has been viewed 7.5 million times.
The self-taught engineer built the contraption in his garage.
It has no brake or seat, but has two accelerators and can be steered. As he says in the video, Furze has no formal engineering qualifications and has never flown before, which makes the feat all the more heart-stopping.
While the flying bike seems to be manoeuvrable, it clearly still has trouble landing. Furze has to use his feet to stop the vehicle, and jump off to avoid being injured by the whirring propeller blades.
