IMMOVABLE CARD.
Upon the face of it, and on first thoughts, it would appear to be the easiest possible thing to blow over an ordinary visiting card placed on a table, provided it be not secured in any mechanical manner. If a visiting card is neatly turned down at the narrow edges, about a quarter or a third of an inch, so that the edges turned down are at right-angles with the remainder of the card, and the card be then placed on the turned down edges, the feat would seem to be still more easy than if the card were simply placed flat on the table. The contrary, however, is the case, and unless let into the secret one may blow at a card so placed for hours without being able to overturn it.
To accomplish the feat, the blowing must be done on the table, not on the card, and at some distance from the card.
