A TOTALLY hands off version of the "Out of this World" effect.
The magician removes a deck from its case. Half the deck is spread face down onto the table, the other half is spread face up. The two halves are then pushed together by a spectator. To be sure that the cards are thoroughly mixed the spectator is encouraged to flip bunches of cards face up and face down until they are content that the cards are truly mixed.
Two cards (one red, one black) are removed to act as indicator cards for the upcoming demonstration. The spectator is then asked to look at both sides of the mixed up deck in an attempt to take a mental snap shot of the face up, face down condition of the deck.
With the chaos of the deck in mind the spectator begins to deal the deck into two piles in attempt to separate the red cards from the blacks. Without any switching or intervention by the magician the SPECTATOR is asked to turn over each of the two piles. Amazingly they have managed to separate each and every red card from each and every black card!
