A few days before this project dip a few large T-shirts into water and fold it up while they are sopping wet and put them into large zip lock bags. Freeze the bags for a day or two. Divide the campers into groups of 5 to 6. Give each group a frozen zip lock bag. The teams need to work together to get the shirt out of the bag and thawed out enough for one of the team members to put the t-shirt on. There are several ways to get them thawed out, but we let our campers figure it out for themselves. Some ideas are: run it under water, microwave it, lay it in the sun-sit on it, etc.
