1x6 - Crowd Control

If you've ever lost your wallet, you'll know the sickening feeling that hits you when you realize it's gone. Behavior change expert Daniel Pink "loses" 30 wallets to test a mind trick he hopes will make people more likely to hand them in. He also helps a fire fighter's charity collect more money, a family business sell more beef jerky and a building cut their energy bills by turning the lobby into a games area.
