Matt plants an umbrella
Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!
Matt initially tried to work out north by licking his finger, before deciding the house would be a north-facing house. He then decided that the task would be a trick task where the answer was where the umbrella was, deciding to impale the umbrella into the ground next to the red mat. He was 37 centimetres away from the correct location, receiving 5 points.
