To pass a hula hoop along a circle of people.
Have the group form a circle holding hands. Ask two people to let go of their grip long enough for them to place their hands through a hula hoop before rejoining them.
The team task is to pass the hula hoop around the circle in a specified direction until it returns to the starting point.
Another way to play is two use two hoops and have them go around the circle in opposite directions.
You can also use loops of rope (about hula hoop size).
