A wrist watch is borrowed and wrapped in a pocket handkerchief. Performer asks if the watch is unbreakable. Before the spectator can answer, the magi starts POUNDING THE WRAPPED WATCH ON THE TABLE. Broken parts are heard to clang around. The magi pleads temporary insanity, and offers to restore the watch. The watch is unwrapped and is found to be unharmed.
Use two men’s white pocket handkerchiefs. Cut a square piece (around 3″ square) from the corner of one hank, and sew it to the corner of the other one, forming a pocket. Inside this pocket put a couple of metal washers, three or four “B-B’s” (get `em at a hardware store), anything else small and noisy you can think of – EXPERIMENT! Then sew all four sides of the pocket securely.
Show hank, the corner with the gimmicked pocket is held in right hand. Push this gimmicked corner into the center of the hank. Place the borrowed watch under the hank (apparently in center), but as hand comes from under center of hank, it brings watch with it, and leaves it at gathered corners of hank. Right hand grabs corners of hank (and watch) and pounds center of hank on table. After the apology, pinch the center of hank with left hand, allowing watch to slide out onto the table, restored and unharmed.
Another idea with this is to steal the watch from the hank (with right hand) as the left hand moves bundled hank forward. The watch in right hand is allowed to secretly drop into your lap. Pound the pieces on the table as above, then shake out the hank showing that the pieces (?) have disappeared. It’s then an easy manoeuvre to slip their watch onto your left wrist under the table. You then bring both hands up, and as your right hand pulls back your left sleeve (exposing the watch), you look at it and say, “there, that entire trick only took 2 MINUTES AND TEN SECONDS, see how time flies when you’re having fun!”
This effect used by KARRELL was one of the hit tricks of his lecture at The British Ring Hastings Convention in 1978 … “Worth the price of the book alone” is an often-used expression but it is certainly true of this effect. An age-old principle is used to bring about a delightful piece of comedy magic in the cleanest possible way.
