Lee fills his helmet with water
Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!
Lee initially tried to shotput a bag of water at the saunas, before he began to tape several sticks together. Midway through, he decided to fill his helmet up with water and throw it over the sauna stones so water would fall on the sauna stones. He made the sauna stones hiss in 12 minutes and 30 seconds, receiving 2 points.
