An English plumber and inventor has begun building the biggest fart machine ever, which he plans to place on top of the cliffs of Dover and aim across the Channel towards France.
Colin Furze hopes the French, 35km away, will hear the ear-splitting blast.
The machine, which Furze will house in a pair of specially constructed buttocks, is a giant pulse valveless jet engine - as used in Nazi V-1 bombs during World War 2 - that creates a plume of fire to go along with its deafening roar.
Furze, from Stamford, Lincolnshire, hopes to mount the contraption on the cliffs of Dover between 6pm and 7pm today.
Furze's previous homemade inventions include pneumatic "Wolverine" claws, magnetic "Magneto" shoes, hand-mounted "Pyro" flame-throwers (all inspired by the X-Men films), an 80km/h pram, and a fire-spurting mobility scooter.
All can be seen in action on his YouTube channel. In his own words, Furze has been "turning the internet up to 11 since 2006".
