Annika eats some watermelon

Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.

Before entering the lab, Annika recruits Mark into eating watermelon with her. However, that is the only bit of preparation she does before entering the lab, and upon seeing that the watermelon is whole, she leaves and searches for something to cut the melon open. Annika spends just over half of her time searching for knives. With Mark’s help, Annika is credited as having eaten 371g of watermelon and comes third.
