Sofie hides a coconut in a box
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Sofie has the idea to hide multiple coconuts in the space. She then shuffles around the entire arena to hide any tracks Mark may be able to follow. Mark checks the unburied coconuts before he starts digging – he just so happens to choose the area where the real coconut is hidden. He reveals that the real coconut has a specific marking on it, which he was looking for. Sofie keeps the coconut hidden for 1 minute 32 seconds, and earns last place.
