Steinar uses nature's beater
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Steinar puts the cream into a bucket, attaches a spade head to a drill, and attempts to whip the cream with it. However, the spade head falls off of the drill, so he replaces it with a forked twig, which proves to be much more successful. He completes the task in around 12 minutes, and earns second place.
