Spider web. Find two trees near each other and take a long piece of rope and going back and forth, make a spider web with small and big holes, before the activity. Take the group out, and tell them they must get from one side of the web to the other, without touching the rope. They have to really communicate, after a few tries, because the little people need to use the little holes, and you need people on both sides to help lift and catch. The first and last person usually uses a lower hole to go through because they have no help on one side...
Clothes line clip. This one goes on all three days. Everyone starts off with a clothes line clip, and it is hooked on their shirt somewhere where everyone can see it. The moment someone says "I can't" or anything negative, the person who hears gets the clip. The person with the most clips at the end is declared a winner. People are amazed at how much negative talk that comes out of the mouth, so easily!
