Rhod doesn't leave the lab

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

Rhod turned off another switch connected to the main switch, claiming nothing would happen when he turned on the switch, not realising that something could be happening outside of the lab. Although he 'completed' the task in 3 minutes and 37 seconds, he received 1 point for getting the answer wrong.
