Divide into teams. Each team forms a line and joins hands. Pass a hula hoop over the first person's head. He has to pass the hoop to the next person without letting go of his hand. The first team to pass the hoop to the other end wins. Or just stand in a circle and pass the hoop around the circle (noncompetitive version).

Or:

Without using your hands, pass a ball from person to person. Don't let the ball touch the floor.
