Have two small balls of string about 40" long. Put players in two teams seated in two circles on the floor; (each dad should sit beside his child). Give one Player in each group a ball of the string and a pencil. On signal, the players in each circle holding the string passes the ball to the person on his right while the starter holds the end of the string. As the ball is passed around the circle, each player takes the ball, winds it once around his free wrist and passes the ball on until the string is all gone. Then the starting player, holding the pencil and other end of the string, begins winding up the string on the pencil. The first team to get the string back on its pencil wins the game.
