The group stands in a circle. The leader has half a dozen balloons. Into each, a message has been inserted before the balloon was blown up. One at a time, a balloon is passed from player to player around the circle, until the leader blows a whistle. The player holding the balloon when the whistle blows must go to the center of the circle. He must sit on the balloon until it bursts, then read the note, and perform the action or answer the question contained in the message.
