Frozen In Time
The magician brings out a clear Plexiglass photo-block. Sealed inside the block is a photograph of a pocket watch. The photo-block is placed inside an opaque plastic cover by the magician and then set on the table.
The performer then has a spectator select any hour of the day, then announce that hour for all to hear. The choice is free and random (No force of any kind is used).
The clear photo-block is then removed from the cover. The audience is shown that the time on the pocket watch, the very time that the photo was taken, it is the exact time named by the spectator. The photo is shown all around. The spectators are asked to feel the surface and verify that it really is a photograph sealed inside. A photograph of a watch, set to their chosen time!
