Get set: Put a ping-pong ball into a two-gallon bucket. Assemble the kids about ten feet away, next to a five-gallon bucket of water.
Cooperate: Give each player a paper cup and tell them that they have five minutes to put enough water into the smaller bucket to make the ping-pong ball float out of the bucket. Let kids try to fill the bucket on their own. If they don't make it within the time limit, explain how a bucket brigade works, then give them another try.
