Simon makes a house disappear with a shovel
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Simon's initial thought is to flush something down the toilet, but he recognises that there is a size limitation on that technique. He then tries out using a smoke machine to fill a bag with mist so that he can create a smokescreen, but that plan doesn't work out for him. He instead falls back on using a shovel to block Mark's view of the Stormester house, claiming that the house itself has disappeared. Lasse places him last in the task.
