A prediction is clearly in view inside of an envelope window. It could be a note, a playing card, a bill, or billet. It can then be switched – undetected, seamlessly, and invisibly. The spectator can be burning your hands – and they still won’t see it happen.
Imagine this: Your audience sees a playing card inside of the envelope window, in full view the entire performance. A participant selects and signs ANY card, then it vanishes completely from the deck. The one card that has been in view since the very beginning is taken out of the envelope – in the fairest way possible – and it is THEIR signed card.
