Modern Magic: A Practical Treatise on the Art of Conjuring

The performer begins by asking the loan of three rings, to be fired from his magic pistol. To preclude the possibility of their being exchanged, he requests the owners to drop them into the pistol themselves. First, however, by way of wad, he takes a small piece of white paper, and presses its centre portion into the mouth of the pistol tube, its edges projecting all round, and forming a sort of cup to receive the rings. Three rings having been offered, and dropped into the pistol, the performer closes over the edges of the paper, and presses them down with his wand, the effect being as if the rings were fairly rammed down into the pistol, though they really remain in the cup, just within the mouth. He now hands the pistol to one of the spectators, requesting him to hold it muzzle upwards above his head. In handing it to him, he places for a moment his own right hand over the mouth of the tube, his palm being flat upon it, and in again removing the hand lifts out and palms the cup (which the projecting edge enables him to do with perfect ease). He has thus obtained possession of the rings. (As the holder of the pistol has been instructed to hold it above his head, he is not very likely to look into it; but lest he should do so, and discover that the rings are already removed, it is well to place in the tube beforehand a piece of crumpled white paper, to represent that which contained the rings.)
