...shower together? I know it's mysteries like this that bring visitors to this website, so I feel obligated to reveal the answer:
After completing a dive, competitors swim to a ladder, climb out of the pool and head immediately to a bank of showers that sit adjacent to the diving boards. Then, in full view of the crowd and NBC cameras, they shower off. Divers keep their suits on, of course, usually appearing only to rinse off their hair and arms. Oftentimes, the divers will receive their scores while still showering off. What's the purpose of this?
