A Changing Card

A DOUBLE-FACED card, say AH-KD, is placed second from the
bottom in an ordinary pack, with the KD side as the back of the card and the real AH on the bottom of the pack.
Thus prepared, execute a riffle shuffle, leaving the two bottom cards as they were. Make the Hindu shuffle, asking anyone to call 'Stop' whenever the spirit moves him. At the word, lift up the packet in your right hand and show the AH. This force is quite convincing to laymen, as it appears that you have stopped at some indifferent card on command. Drop the packet on that in your left hand and order the AH to turn over. Spread the cards and the KD side of the double-faced card shows. Something has evidently gone wrong so you take out this KD, keeping it face up and cut at that point thus secretly bringing the AH to the top of the pack. Take out any two cards and put them face to face with the KD face up between them. Snap a rubber band round the three cards, turning them over in the process.
Order the recalcitrant AH to appear face up between the two cards and the KD to return to the pack. Remove the rubber band, the AH is between t them face up. Pick up the pack in your left hand and throw out the two unprepared cards to be examined. Make the bottom change, taking the unprepared AH from the top of the pack and throw it down.
Palm the double card from the bottom in your left hand and spread the pack face up showing the unprepared KD amongst the other cards. Pocket the double card.
