Two sets of 10 cards are counted out fairly and openly onto a spectator's hand before being dropped into two glass tumblers where they can be clearly seen. One at a time three cards are invisibly moved from one glass to the other, and when the piles are counted back onto the spectator's hand again, the first glass only contains 7 cards and the other 13.
This is the classic cards across effect using a method that is completely move and sleight free. Everything happens at fingertips and there is no palming required, nor any special counts. Designed for a close-up or intimate parlour show, this routine is so open and fair looking that it seems impossible that three cards could migrate from one pile to the other. And yet they do!
[Note: You will need some roughing compound, for example a roughing stick or spray.]
