Tell-Tell Watches by Devin Knight & Ulysses Frederick Grant

EFFECT: Any three people take ordinary watches the performer provides to a far corner of the room and set them to any hour and minute. They in turn each wrap their watch in a small opaque paper bag. These are placed anywhere and you can divine the exact hour and minute on each watch. No gimmicked watches or electronics are used. At the end, everything can be fully examined and nothing will be found amiss.
