A great cool-down game, the participants must work together to complete this task. All you need for this game is a tarp.
To build teamwork and cooperation amongst the group.
Have the group of children stand on the tarp and challenge them to flip it over without anyone stepping off of it. Fold the tarp in a manner that challenges the group adequately. The trap must be flipped over completely without any of the participants stepping off of it.
Use a smaller (or pre-folded) tarp if the group flips the tarp easily.
