3 simple matchbooks for a mental miracle and an easy free drink! Effect: three matchbooks are set in front of the mark. While you turn around (or even leave the room!), he's invited to grab any matchbook and sneakily remove one match from anywhere, and replace the matchbook on the exact same place. Once you turn back around, you pick up each matchbook and weigh it in the palm of your hand. After holding up each one in turn, you boldly (and correctly) reveal which matchbook is missing a match!
