Maybe what would be cool would be that the person, after doing their dive (let’s say, a reverse 1 and a 1/2 somersault with a full twist) would then be required to scuba dive underwater, trying to locate a hidden coin that was shot into the pool while they were doing their dive. They could be scored on how quickly they find the coin, and how gracefully they find it.

sounds like a good idea but scuba equitment is heavy so the diver would be weighd down when diving but other than that its cool
