Adrián Carratalá has jealously guarded the secret with which he managed to fool Penn & Teller. Now you too can amaze your audience with this miracle!

Effect: A borrowed ring disappears under a handkerchief and immediately appears tied to the magician's shoelace.

And this is the best of all:

• The magician never approaches the shoe.
• It doesn't depend on clothing. It could be presented completely naked (only with shoes, of course).
• The gimmick is installed in 5 seconds, and the routine resets in another 5 seconds.
• The entire system is self-contained and fits in a pocket.
• No duplicate rings are used. The ring held by the spectator is their genuine ring.
• There are no steals or suspicious movements; hands are shown empty at all times.
• No reels, threads, or elastic are used. The gimmick is designed for professional use.
