A group of friends participated in a challenge called the "mystery pool punishment." They stood in front of multiple pools with unknown contents and took turns jumping into a randomly selected pool. The contents of the pools ranged from harmless (such as Orbeez, bubble wrap, and shaving cream) to disgusting (such as rotten fish, expired milk, and cat pee). The friends continued to jump into the pools until all numbers had been used, and then they let some subscribers judge who was the messiest. The person deemed the messiest would have to jump into the ultimate mystery pool punishment.
