Giant game day! Human Battleship: have people sit in two grids, put a tarp between the two grids, each person gets a chance to throw a water balloon over the tarp. Other giant games could include Hungry Hungry Hippos with laundry bin, balls and carts; human chess; and marbles.
Human Giant Game Day
Reconnect with childhood games. A day of fun for people to come. A different organization can sponsor a game and help with community awareness. Community teamwork, team-based organizations.
Its great having Human Giant Game Day, but would be amazing having at least one giant chess or checker; etc. Always available in a public space or environment for the people and families.
