About This Book

A collection of practical, theatrical experiments and demonstrations designed to amuse and astonish audiences, presenting clear, step-by-step instructions for optical illusions, chemical colour changes, simple mechanical contrivances, engraved relief work, and staged effects involving small animals and household materials. Each chapter explains the method of execution and the observable result, often noting how presentation and concealment enhance surprise. The work aims to enable performers and curious amateurs to reproduce entertaining physical phenomena with modest apparatus, while distinguishing easily executed tricks from those that require greater dexterity, mechanism, or preparation.

CHAP. X.

How to dispose two little Figures, so that one shall light a Candle, and the other put it out.

Take two little figures of wood or clay, or any other materials you please, only taking care that there is a little hole at the mouth of each. Put in the mouth of one a few grains of bruised gunpowder, and a little bit of phosphorus in the mouth of the other; taking care that these preparations are made before hand.

Then take a lighted wax candle and present it to the mouth of the figure with the gunpowder, which taking fire will put the candle out: then present your candle, having the snuff still hot, to the other figure; it will light again immediately, by means of the phosphorus.

You may propose the same effect to be produced by two figures drawn on a wall with a pencil or coal, by applying, with a little starch or water, a few grains of bruised gunpowder to the mouth of one, and a bit of phosphorus to the mouth of the other.
