A US inventor has created a 70mph, jet-propelled toilet. Inventor Paul Stender, 43, made it out of a rickety old portable toilet and a 1,000bhp Boeing turbine engine bolted on to a go-kart chassis. The 70mph jet-propelled toilet /Pic Paul Stender Two tiny holes in the door let him see where he's going - as a 30ft fireball roars out the back of the £5,000 machine. Paul, who also has a jet-powered motorbike, takes the Port-O-Loo to thrill crowds at race meetings near his home in Indiana. He said: "I used to keep a toilet roll inside to make it look really authentic. "But I soon found that wads of paper got sucked into the engine which was dangerous. If it sucks in paper it could explode - and me with it."
