SPANISH LECTURE BOOK Más allá del efecto
Window to the future by Henry Evans
One of the last effects of Henry Evans that surprises everyone in his conference
The magician places a group of cards in a transparent glass as a prediction and brings on stage a different colored deck from which he draws a group of cards.
This group is mixed American style by a spectator and separated into four groups of different amounts by the magician.
The spectator is invited to discard the groups one by one, until only one package is left on stage, which is mixed once more by himself.
The first effect occurs when the number of cards in the set chosen by the spectator matches the prediction.
The second effect occurs when the exact order of the cards in both packs is perfectly matched even after the spectator shuffles.
