TAKE THE TREASURE
Invite the young people to sit in a large circle. Place a chair in the middle. On the chair place the treasure. A set of keys works really well. Ask for a volunteer to guard the treasure from thieves and give them a rolled up newspaper. Unfortunately, they have to do this while being blindfolded!
Once the guard is in place beside the chair, a thief is quietly chosen from the circle. They must attempt to sneak up to the chair and without alerting the guard, snatch the treasure.
Meanwhile, the guard listens for the thief and trys to swat him with the newspaper baton. If the thief is swatted, he must return to the circle. If he succeeds in stealing the treasure and returning to the circle, his prize is to become the new guard.
