Simon rubs a cauliflower against some polystyrene

Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.

Simon first rubs an inflated balloon against a large piece of polystyrene, and then rubs a cauliflower against the polystyrene, creating two irrititating squeaking noises. Lasse finds the noise viscerally uncomfortable, so awards Simon first place.
