This is another classic pool game that doesn't require any special props or toys. The object of the dolphin game is simple: Try to swim the farthest distance underwater. Two or more people begin on one side of the pool. On the count of three, they submerge, kick off from the wall and try to swim all the way to the other side without taking a breath. Strong swimmers can do a flip turn on the opposite wall and attempt to swim back. The person who swims the farthest without taking a breath is the winner.
Again, please use caution when playing any game that requires you to hold your breath. There have been cases where children who have repeatedly held their breath underwater have passed out and even drowned. Pool safety advocates call it shallow water blackout [source: Margetts]. Adult supervision is always recommended when young people are playing in a pool.
