Jessica eats no watermelon
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Jessica enters the lab with several tools she thinks may be helpful: a knife, a large spoon, a pitcher, and a stick blender, intending to drink a watermelon smoothie. She cuts the watermelon open and uses the stick blender to blend the inside of half of the watermelon; unfortunately, when she asks Nuno how much time she has left, he informs her that her time has passed. Jessica eats a total of 0g, and comes last.
