You show four queens. The two black queens are placed on the table, the two red queens are retained in the hands. But despite this separation, they change places and the red queens are now on the table and the black queens are in the hands. The next phase is a little 'oil and water' sequence where the queens are mixed black, red, black, red but quickly separate themselves again into two black and two red queens. The startling climax is that all four cards change their back colors.
