latestmagicbeing00hoff.pdf | 36 | 20 LATEST MAGIC The utility of the black art mat, however, does not depend upon the pocket only. Its unbroken or "plain" side, or indeed a mat wholly without pockets may also be very effectively used for van- ishing purposes. In this case a little auxiliary appliance comes into play. This is a small velvet patch, serving as an "overlay." It may be round or square, according to the purpose for which it is intended to be used. For coin-vanishing purposes it is best circular, and about two inches (or less, as the case may be) in diameter. The foundation is in this case a disc of thin card covered on both sides with velvet, in colour and texture exactly cor- responding with that of the mat, under which con- ditions the patch, when laid on the mat, will be invisible. The exact similarity of the two surfaces is a point of the highest importance for black art effects, and the velvet used, if not actually silk vel- vet, should at least be of the silk-faced kind. Vel- vet which is all cotton will never give satisfactory results. If a coin be laid on any part of the mat the performer has only (in the supposed act of picking it up) to lay the velvet patch over it to render it invisible. If it is desired to reproduce the coin, a handkerchief shown to be empty, may be laid over the patch, and a moment or two later picked up again, bringing away the overlay within it, and again revealing the coin in statu quo. A practical example of the use of this device will be found in |
