USES OF ALCOHOL.
We put some sugar into water; the children see that it melts; then some
glue or shellac is placed in the same liquid; they see that this is not
melted, but that, when alcohol is used instead of water, the glue or
shellac is dissolved. From this experiment they learn that alcohol is used
in making varnishes.
Some water is poured into one saucer, and alcohol into another; a lighted
match is applied to each; the class notices that the alcohol takes fire and
burns, while the water does not.
Next, we fill a lamp with alcohol, and put a wick into it; when the wick
becomes wet with the fluid it burns steadily and without smoke, as may be
seen by holding a clean white saucer over the flame. This shows why
jewellers and others, who wish to use a lamp to make things very hot,
prefer alcohol to kerosene, which, as the children know, smokes
lamp-chimneys, or anything else, so easily.
