Simon catapults a shoe into a bathtub
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Simon frantically tries to build a catapult out of a toolbox and various flat surfaces from the shed. For each flat surface that does not get the shoe into the tub, he makes a show of throwing it away. He considers using Mark as a backboard, but decides against it (“that’s not cool”). Simon eventually uses a skateboard as his launch surface, which comes close to the tub, so he continues trying with it. He eventually manages to launch a shoe into the tub. Simon finishes in 5 minutes 26 seconds and comes second.
