The perfect open prediction…”
Do you believe in fate or destiny?
You remove an envelope from your pocket. It is sealed. There are no secret compartments or hidden flaps. You explain that inside this envelope, there is one prediction. One card, sealed. No matter what the spectator says or does, nothing can change the outcome. It is fate. It is determined.
You give the spectator a deck of cards. They examine. They shuffle.
You are completely sure of your prediction, and to prove it, you tear open the envelope, showing a face down card. You are committed. And to make things even MORE fair, you turn the card over. They see the identity. They see the future.
