Jukka uses the wall to open his coconut
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Jukka initially chooses to use the pliers.
In an attempt to open the coconut without incurring any time penalties, he then takes it outside and simply throws it at the wall to break it open.
He is therefore disqualified for not using any of the supplied items.
