Vanishing Martini Bottle

The magician displays a Martini Bottle sitting on his right palm. The bottle is in plain view of the audience. The magician explains he will make the bottle disappear by a mere snap of the fingers. He does so and convinces himself that the bottle is gone. However, upon looking at his right hand, he finds the bottle is still there. He then explains he made a mistake and forgot to cover the bottle with the cardboard tube (only half the size of the bottle). He does so and again snaps his fingers to find the bottle still has not vanished. He now explains he forgot to cover the bottle with the handkerchief. He now covers the bottle and tries again. Upon removing the handkerchief, the bottle is still there. Again he apologizes and explains he will forget about the trick and the proceeds to clap his hands over the bottle. The bottle disappears in plain view of the audience. He then shows his hands and the tube completely empty!
