What is an aerosol?

An aerosol of fine particles of liquid or solid substances suspended in the air, or in any other gas. It is not, as many people think, merely a spray for use in applying paint easily, or getting rid of unpleasant smells.

The germs of diseases, for example, are to be found suspended in the air, and these dangerous aerosols can be dealt with by spraying chemicals to form another aerosol which destroys the germs. Leaves of plants attacked by pests can be treated in the same way.

Chemical in the container part of an artificial aerosol spray are stored there under very high pressure. When the release trigger is pressed a valve opens, and the chemicals are forced out through a tiny hole in a fine spray. This invention is useful not only in the home, and to gardeners and doctors, but also to a wide variety of specialist users.
