Going to make "Natural Pools" in my future pond.
As a kid we had a game where we would jump on the trampoline with a large exercise ball (like
https://cozzy.org/best-rectangle-trampolines/ ) The object of the game was to get the other players "out". To get someone "out" you threw the ball at their feet while they were in the air which usually resulted in them landing on top of the ball and getting flung off the trampoline. Anyone who fell off the trampoline in this way was "out" for the rest of the game.
