One-handed paper aeroplanes

Teamwork
Break into groups of about 3 or 4 people. Everyone then raises their dominant hand, you know, the hand you use to write with. Now, everyone puts that hand behind their back and are forbidden to use it for the activity. Each group then has 5 minutes to work together without their dominant hands and build a paper airplane. The goal is building a plane that will compete in a contest to see whose plane can fly the furthest.
