A game testing teamwork and co-operation
Invite everyone to stand in a circle shoulder to shoulder. Each person then turns to the right to face the back of the person in front of them. Ask them to place their hands on the shoulder of the person in front. On the count of three, they slowly begin to sit down on the lap of the person behind. As long as everyone is helping the person in front of him or her to sit, then everyone should be supporting the weight of everyone else. Of course, should someone slip, the game becomes 'human dominoes.' It might take a couple of attempts to complete the challenge.
