Unexpected Disappearance in Magical Experiment.

By nature, a magic demonstration involves the unexpected. This is the element that causes the 'OMG' reaction. But every now and then, a magician will tell you what is about to happen. But beware. If a magician tells you what to look for, he/she is probably fooling you. The scenario depicted here is just such a case. The magician directs the attention of the audience to a coin, which is covered with an inverted glass tumbler. This in turn is encased in a paper napkin or serviette. The audience is told that the coin is about to disappear. When this fails to occur, the magician (not wanting to disappoint) causes the glass tumbler to vanish instead. This is a very simple trick that any-one can perform at their next gathering. Full instructions are provided in the video.
