Nikolaj changes the state of the pineapple

Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!

Nikolaj liquidises the majority of the pineapple and pours it into a bag which he hides inside his trousers. He openly holds the crown of the pineapple in his hand during his inspection. Mark guesses correctly 4 times and incorrectly just once, so Nikolaj comes last in the task.
