Have the group stand in a circle with their hands behind their backs. Choose an object, like an orange, and tell them that it must be passed all the way around the circle; however no one may use their hands. Before you begin, have the group brainstorm ways to do this and pick one that everyone agrees on to try. Examples are holding it under their chin, between their head and shoulder, and using their feet. Once everyone agrees on a method, pick a person to start and begin the relay. Play a few rounds and try to beat your time or try a new method of passing the object around.
An orange, softball or similar sized object
