Multiplied Money.
Take a large drinking-glass, of a conical form, that is, small at bottom and wide at top, and, having put into it a dime, let it be half filled with water; then place a plate upon the top of the glass, and turn it quickly over, that the water may not get out; a piece of silver as large as half a dollar will immediately appear on the plate, and somewhat higher up another piece of the size of a dime.
