Ask participants to kneel on the floor in a circle, link their arms (elbows) with the people on either side of them, and place their palms flat on the floor in a line (so that each person’s hands aren’t connected to each other, but to other people’s hands). Now ask people to slap their palms on the floor, in turn, to create a ”wave” that goes around the circle. Having linked arms makes it difficult to figure out which hand is your own! If someone makes a mistake, they have to put one hand behind their back, and the game continues. If they make a mistake again, they are out of the circle.
