Vanishing Oil and Water by Wild-Colombini Magic - Trick

A great and unique variation of a classic.

Four black cards (say four 2C) and four red cards (say four 9D) are shown. The cards are mixed together (alternated à la Oil & Water). Magically the black cards disappear and all the cards are seen to be red! (The cards are shown on both sides, the black cards are REALLY gone.)

No lapping, no palming, no rough and smooth! You'll be amazed by the clever method. Complete with all the cards.
