Place a dispenser (such as a cigarette, soda, or snack machine) in the room that contains something players need (for example, a bottle of water to use in another puzzle). Players must find a coin or slug to access the object. Alternately, players must find another way to access the object. [Note: Make sure the machine is bolted to the floor to prevent players from accidentally pulling it over on themselves while trying to get the object out.]
