The performer introduces six cards: three red spot cards that are red-backed and three black spot cards that are blue-backed. The cards are shown one at a time as they are mixed in red-black order; thus, the backs of the cards are also mixed in red-blue order. Then, without any false moves, the cards are shown to have instantly separated! This is repeated a second time! This routine is concluded by explaining that the cards will naturally separate since oil and water cannot be mixed; the red and black cards are now spread onto the table and are obviously seen separated in color, both faces and backs. This time, and again without any false moves, the cards are shown to have become instantly mixed! Includes instructions. Excellent condition.
