Choose three students to be "it" (depending on class size). The rest of the class gets into a scatter formation. If a student is tagged, they must go down on one knee and stick one thumb up in the air. In order to be set free, another student must sit on the knee of the tagged student and flush the toilet (pull down the thumb in the air) and yell "whooooosh"! Stop the game before the excitement level drops so the kids want to keep playing it again next time.
