Modern Magic: A Practical Treatise on the Art of Conjuring
Professor Hoffmann61TO SPRING THE CARDS FROM ONE HAND TO THE OTHER.--This is a mere flourish, and belongs rather to the art of the juggler than to that of the magician; but it is so frequently exhibited by conjurors that a work on magic would hardly be complete without some notice of it. The cards are held in the right hand, between the tips of the second and third finger at the top, and the thumb at the bottom. If the thumb and fingers are now brought slowly nearer together, so as to bend the cards slightly, they will one by one, in quick succession (beginning with the bottom card) spring away from the pack; and if the pressure be continued, the whole of the cards will spring away one after the other in this manner. If the left hand be held at ten or twelve inches distance from the right, with the fingers slightly bent, the released cards will be shot into the left hand, which, as the last cards reach it, should be rapidly brought palm to palm with the right, and square up the pack to repeat the process. By giving the body a quick half turn to the right as the cards are sprung from one hand to the other, you may make the hands (and with them the moving cards) describe an arc of about two feet, and so deceive the eye of the spectator into the belief that the hands are that distance apart, though in reality, as they both move together in the same direction, they retain throughout their original relative distance of ten or twelve inches.
