For this a special tumbler will be required. It is a large one, with perfectly straight sides, and is furnished with an outside cylindrical shell, also of glass, which is not discernible from the glass itself when in position. This outside shell must be sufficiently large to slip over the hand of the performer, so it will be seen that it is of considerable dimensions. This fact is always of value from the point of view of effectiveness: the larger the article the performer can manage to successfully manipulate, the better. The performer advances with the glass and shell together, and fills the former to the brim with water. He then places the whole on the rear edge of the table, and covers with the cloth. Grasping the shell, from the outside, with one hand, and placing the other hand below, the glass is slid gradually off the table, when it will drop through the shell into the hand of the performer, which places it upon the shelf. The more rapidity there is employed, the better. The performer comes forward with the shell inside the cloth, and allows the audience to feel its shape, and also taps it with the wand, to make the glass ring. He cannot allow the shell to be actually seen, as the absence of any water would be at once noticed; but the satisfying of the senses of touch and hearing will be sufficiently convincing. Retiring to about the centre of the stage, the performer thrusts one of his hands through the shell, from the bottom, and, whilst supporting the card shape with the fingers, allows the shell to glide down the arm, inside the coat sleeve. The handkerchief is then shaken out, and shown to be empty. In this case, the glass is not reproduced, the trick depending for effect upon the apparent bringing of a very large glass, full of water, amongst the audience, and causing it to vanish before their eyes. In the first method, there is no tapping of the sides of the glass when in the handkerchief, or any feeling of its shape, which is, of course, a very great feature of this method. The cuff must be gripped by the third and little fingers, when the arm may be dropped without any fear of the glass shell falling to the ground.
