Pen Twister
The magician puts a pen on the outstretched fingertips of a spectator, and covers it with a transparent plastic card. The pen is clearly visible under the card. After a moment, the magician rotates the card and makes the center of the pen completely disappear. The spectator will see the center of the pen visibly vanish, and he will now clearly see only his fingers under the invisible pen. He can even open and close his fingers… the center of the pen will have become completely invisible! The magician now rotates the transparent card back to its original position, and the center of the pen reappears. As a super climax, the magician rotates the card slightly to the left and slightly to the right claiming that he will magically twist the center of the pen… and incredibly when he removes the transparent card, the pen, that was always in the hand of the spectator, is clearly twisted in its center!
