Steinar pops the balloon
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Steinar decides to pop the balloon with a staple gun, and then quickly realises it was a bad idea. He then hangs the remnants of the balloon over a tree branch while peeling some - but nowhere near all - of the potatoes in the box. He earns no points because he did not make the balloon float.
