Keep the pictures handy throughout the day to refer to as kids identify things about themselves that they don't like. Dip it into chocolate and while one kid is lying on her back, have another kid try to feed the donut to her. The donut usually bounces around like it's drunk, getting chocolate all over the person lying down. The game leader and mind reader are accomplices who know in advance how the game is played and what the code or trick is.
Kids are to try to guess what the code or trick is.
As soon as someone thinks she has figured out the code, let her try to lead the game correctly. Keep going until most kids have caught on or until you decide to reveal the code. While the mind reader is out of the room, the crowd chooses three objects, one of which is to be identified by the mind reader as the chosen object. When the mind reader returns, she is shown all three objects one by one, and then identifies the correct one. Choose campers who will get into the activity.
