Solveig shoves the balloon in a hedge
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Solveig initially considers putting the balloon in the pot of water, but eventually decides on shoving it in the hedge and leaving it there. Immediately after she starts peeling, the balloon falls out of the hedge and quickly hits the ground, leaving her with only one eighth of a peeled potato. Despite this, she earns second place for being only one of two people who had, in Atle’s judgment, made the balloon float in any way (i.e. the very brief period during which it was falling out of the hedge).
