Touch the Ball
I learned this game during my time at the Barrier Island Environmental Education Centre.
You will need a variety of objects in a variety of sizes; some good examples include a soccer ball, a softball, a tennis ball, a golf ball, a tube of lip gloss, a bread clip, and a dime. Ask your group to stand in a circle. Place the largest object in the middle of the circle, and tell the girls that they must all touch the object without touching each other. Once they figure out how to arrange themselves so that they can do this for 10 seconds, give them a smaller object. Work all the way down to the dime!
