This document describes an underwater sport called "vortex diving." There are two players who must find a hidden vortex (fruit holder) underwater and activate it using a hand mixer (key) to create an underwater whirlpool. The first player to activate the vortex wins the match, and the best of three matches determines the overall winner. Players must dive into the pool when signaled and locate the vortex while avoiding obstacles in order to insert their key and turn it on to start the whirlpool.
