immediately afterward produced from the ears, or any part of the body that fancy may suggest.
The balls are small pieces of camphor cut to shape, and are lighted in the flame of a candle. They should be tossed from one hand to the other, and finally into the mouth, which should forthwith be closed. This, of course, extinguishes the balls, which should be secretly removed at the earliest opportunity.
The reproduction of the balls of fire is managed with the aid of the acid tubes mentioned on p. 160, which, together with a small quantity of the powder, should be wrapped up in flash paper, and deposited about the person as required. The best effect, however, is obtained by producing them from behind the ears; it is also a very convenient method, as the tubes are not so likely to be prematurely fractured.
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.
