For this game you will need some hula hoops.
Pick 2-4 players to roll hula hoops that will be positioned across the width of the play area.
Have the rest of the players line up across the length of the area.
Players will run from one end to the other without being tagged by a hula hoop being rolled across the width.
If they are tagged they help rolling new hula hoops across until there is a champion!
