For this game you need a single pacifier (the kind with a loop handle) and a pencil for each guest.
Have your guests put the pencils in their mouths and their hands behind their backs. Place the pacifier on one player’s pencil, and have them pass the pacifier from one person to another without using their hands. If someone drops the pacifier (or the pencil) they are out. Play until only one person remains.
The winner should get a prize. A pen/pencil set is a nice choice for this game.
