nail Pooping Tie in any child or children to turn a rope (not too long) to the waist with an attached nail. Put an empty bottle (coke bottle or something more complicated: a beer bottle) on the ground. The children try to put the nail in the bottle "to defecate". The child who is the fastest wins. You can also specify a time limit, for example, by saying: "Who the nail most often in the bottle gets in 3 minutes wins).
