From the product description: Joe Miranda and Julio Montoro, the duo who showcased extraordinary creativity with "Leviosa," have teamed up again. This time, it's an impossible transposition of a signed coin (10-yen or 100-yen coin). Have the spectator A sign the coin and hold it. Separately, have spectator B hold a key with a smart tag (GPS tracking device). While checking the GPS screen on your smartphone to confirm the key's location... suddenly, an error message appears indicating the battery is dead. When spectator A opens their hand, they find the smart tag's battery instead of the coin. When spectator B removes the battery from the smart tag, the spectator's signed coin appears inside. The innovative aspect is using the smart tag as the destination. The moment of the transposition can be presented very naturally. There's no need for dramatic effects like fire. The bug in the smart tag tracking screen alone creates surprise and builds anticipation. This simple presentation is modern and perfect. No consumables are required. The Joe Miranda-made loader is also innovative. You can easily load the signed coin just by dropping it. You can retrieve it with the action of taking the key out of your pocket. The necessary error screen video can be downloaded online to your smartphone. Always carry the modern version of the impossible transposition of a signed coin.
