Presto! The coin is dropped into the glass and heard to jingle. When the handkerchief is removed the half-dollar has disappeared, apparently dissolved in the water. This very effective trick is accomplished by means of a glass disc of the same diameter as a half-dollar. The modus operandi is as follows: Borrow a half-dollar and while holding it in your hand throw a handkerchief over it. Under cover of the handkerchief exchange the coin for the glass disc which you have concealed in your palm. Now get some one to hold the disc by its edges through the handkerchief, directly over the glass of water. He naturally supposes that he is holding the coin. Pronounce your magical phrase, and command your volunteer assistant to drop the half-dollar into the glass. It will fall with a jingle similar to that of a coin, and will lie invisible at the bottom of the glass. You may even pour off the water, but the disc, thanks to the power of suction, will remain in the same position, firmly attached to the drinking-glass. To complete the effect the genuine half-dollar should then be produced from under the table or from the pocket of the volunteer assistant.
