The youth sit in a circle. One person goes outside the room, while he is away the others decide what he should "be" when he comes back. He has to ask each youth member in turn what he has to buy for himself. One may say black boots, another a whistle, another a flashlight, etc. If the shopper goes right around the circle without guessing what he is (policeman), he must go out again, and the campers will choose something else.
