rubbers on radiators
Quietly placing a rubber on a radiator at the beginning of the lesson will create a creeping junkyard stench. By the time it reaches the front of the class and the teacher, fellow pupils will have been chuckling and retching for minutes. By the time the teacher does become aware of it, the room is full of stank, and there's nothing anyone can do.
