Tandem

The transposition happens practically in the spectator's own hand, which is what sold me. I've been doing coin magic for years and the cleanliness of this method caught me off guard.

I signed the coin and handed it right back to them, and they still watched it jump from one hand to the other. There's no palming or funny moves—the transposition just happens clean, which is why I've been carrying it everywhere.

The "hands-off" aspect is what sold me—there's no awkward cover-up or suspicious reaching, the coin just visibly switches under impossible conditions. I've performed it for laypeople three times this week and each reaction was a genuine gasp.
