Experiment has proved that if water is allowed to fall upon a rising current of air that is rapid enough to break it into drops, the drops become positively and the air negatively charged. It is well known that the formation of the cumulus cloud, called a thunder head, is caused by an uprush of warm, vapor-laden air into the cooler upper atmosphere. This gives rise to a turbulent condition in the clouds, which seem to be "boiling," or rolling over and through each other, and sets up such a condition that the raindrops formed become electrically charged.
