To Light the Gas with your Finger,

turn it on without applying a light, walk around the room, sliding your feet over the carpet, until you again reach the burner, touch the tip of the burner and instantly the light will blaze up as if by magic.

From what has been already said, the reader will understand that the gas-jet experiment is only successful under peculiar conditions of the atmosphere. Do not try to turn on the gas with one hand and light it with the other, for as soon as the first hand touches the metal key the electricity is expended, and there is none left in the other hand to ignite the gas. Turn the gas on first, walk around the room in the manner described, and touch nothing with your hand before it is applied to the burner.

There are many other experiments that may be tried by boys interested in this subject, but as they necessitate more or less complicated and expensive instruments they are omitted, it being the object of this book to describe only such things as can be manufactured by the boys themselves.
