Exploding Soap-bubbles.—This is a novelty, and will be found to produce a very good effect. The bubbles are blown in the usual way with an ordinary clay pipe, the only preparation necessary being that the bowl of the pipe must be filled with cotton-wool soaked in gasolene. Bubbles blown with a pipe thus prepared will be found to explode in a flame when approached with a light.

The Tube and Ball.—This is a very ingenious trick, and well worth the attention of the most fastidious performer. It can be used in several ways.

Fig. 36.-Tube and Ball

The apparatus consists of a piece of one and one-half inch brass tubing about seven inches long, with a cap of the same metal fitting loosely over one end; also two billiard balls about the size of the diameter of the tube. The audience, however, are not supposed to know of the existence of more than one ball. (See Fig. 35.) The tube and cap, together with the ball, are given for examination, attention being drawn to the fact that the ball will readily pass through the tube. After examination the tube is stood on one end on the table and covered with the cap. The operator then takes the ball and vanishes it by means of sleight of hand, when, on the tube being raised, it has to all appearance been passed underneath.

The secret lies in the fact that there is a very small dent in the side of the tube at the centre; also that one of the balls—that given for examination—is slightly smaller than the other. The small ball runs freely through the tube, but the large one will not pass the centre on account of the indentation.

On receiving back the tube the performer secretly drops the large ball into it, which, owing to the force of the fall, is pinched in the centre and will not fall out. In this condition the tube can be turned about in all directions and will still appear empty. When placing it on the table the performer is careful to bring it down rather smartly on the end at which the ball was introduced, when, owing to the concussion, the ball is released and falls on the table.

The tube can be used to cause the disappearance of a ball in the following manner:—Place the ball on a tea plate and cover it with the tube, which in turn cover with a second plate. By reversing the position of the structure the ball falls into the tube, where it is retained in the manner described, and after a little more twisting and turning, to add to the general confusion, the plates are removed and the ball is proved to have disappeared.

The ball can of course be reproduced if desired; or if two tubes are used it may be, apparently, passed from one to the other. In this case, however, it is suggested that round discs of wood be used in place of the plates, as the latter would be likely to get fractured in the act of bringing the tube down with sufficient force to dislodge the ball.

The Ubiquitous Thimble.—This is one of the prettiest sleight of hand tricks in existence, and requires very little practice. For the purpose of the trick, in its entirety, the performer must be provided with two thimbles exactly alike; but very many surprising passes can be made with one thimble only. The idea of the trick proper is to cause a thimble placed on the forefinger of the right hand to disappear and be found on the corresponding finger of the left hand, without the hands approaching each other. It is usual, however, in the first place, to execute a number of passes with one thimble only, as by this means the audience will be the less likely to suspect the introduction of the second one. The main thing necessary is to acquire the knack of holding a thimble in the fleshy portion of the hand at the root of the thumb, in which position it can be placed, or removed at pleasure, by simply bending the forefinger. (See Figs. 37 and 38.) This sleight must be executed with equal facility with both hands.
