Here’s what happens:

A stunning long-distance surprise, using materials that the participant has around the the house: three pieces of paper, a pen, a coin, and a key. A game is played, with the materials out of the performer’s view. Objects are moved and switched, with enough freedom of choice that there’s no way the performer could know the position of anything. And yet, the final item is not only revealed, the performer proves that it was secretly predicted well in advance.
