Wearing a snug fitting Chelsea football kit, London Gunge Fan takes a seat in the gunge tank (you just know pink gunge is coming). He has 4 minutes to make his way along the entire buzz wire game without setting it off. Every time he makes contact with the wire, the buzzer sounds and he's gunged and has to go back to the start. If he fails to get to the end within the time limit, then the full tank of thick pink gunge above him is released.
