A routine with a minimalist technique, but with a baffling effect. It's ideal, isn't it? The routine is kept simple, while raising the tension: we start with "The obvious", then "The interesting" and finally "The Amazing". And indeed, it is!  

You borrow a ring and a shoelace, the most ordinary. You announce that you will be able to put the ring on the lace, without the ends leaving the viewer's sight... A scarf is placed over the middle of the lace and the ring. The magician goes under the scarf, without the ends moving. And unbelievable: the ring is tied on the shoelace! You MUST try this clever trick.
