balloon game for cooperating, giving another happiness

at some conference, people were asked to enter a room filled with filled balloons. Each person's name was on one balloon. They were asked to find their own balloon in five minutes. Chaos ensued and in five minutes, no one had found their balloon.

Then the facilitator asked everyone to find one balloon, any balloon, and give it to the person whose name was on it.

This would be fun to do, demonstrating collaboration and giving happiness to others. In giving happiness, we receive it.
