This was manufactured in Switzerland by Yrus, unfortunately they have closed their business and we have only this one set! I like the props supplied with this trick a lot. The basic presentations is that you hand the spectator a small wooden box that has a clock-face in it. The spectator is asked to secretly set the dial to any hour he likes and close the box and place it on the table. You have a matching box and set your dial at what you say is your prediction at the same time. you place your box on top of the spectators box and reiterate what just happened. The spectator is then allowed to open both boxes and sees that the prediction matches. This can be repeated immediately. Instructions highlight other routines that can be done with these props.it is also not necessary to place the boxes on a table, the spectator could hold both of them in his hand (so could you). Imported from Switzerland. Routine by Philius.
