Annika draws a big circle
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Annika ties a rope to a tree in the middle of the Stormester yard, and ties a can of spray paint to the other end. She then slowly and methodically sprays a circle into the grass. Because Annika used an unmovable centre (unlike Jakob), and kept the line taut (unlike Jakob and Mahamad), she ends up with a very circular circle. Annika wins the task.
