Pipe Down
Toboggoff writing

The contestant starts on a platform raised several stories in the air. Connected to this is a long fabric tube that leads down to the ground. 

The contestant has to get into the tube and slide down it. Near the bottom is an opening in the material. Under this is a platform floating on a lake. 

When they reach the opening, the contestants have to drop out of it and try to land on the platform. If they time it right, they'll land safely on the platform and win the game; but if they're too fast, or slow, the contestants will end up in the water and will have lost.
