Today at work I was in charge of organizing a team-building activity for about 25 people. I had people get into groups of 3 and try to build the tallest possible structure using only gummy bears and toothpicks. Then I measured the height of each group's structure after 10 minutes.

I was worried about how the activity would turn out, but it ended up going pretty well. Of course, the best part about organizing the activity was not having to actually do the activity.
