Meet Colin Furze, a mad inventor from Stamford, Lincolnshire.
Now, the 32-year-old plumber-by-trade has created his ultimate machine. A rocket powered go-kart.
The video below shows Colin - who loves prancing around like a sugar-soaked eight-year-old - taking his latest invention for a test drive at what appears to be a local airfield (a sensible move, given the flames it chucks out the back).
Suffice to say, you don't see his rocket-powered kart go round any corners. Though we fear Colin may have gone round the bend himself some time ago.
