Rubber is well known to be an excellent insulator of electricity, but one would hardly experiment with rubber as a generator of electricity. Nevertheless, it has been found that an ordinary rubber band can be used to generate either, a positive or a negative charge of electricity. A piece of hard rubber can be charged by friction, but the rubber band produces its charge in a much simpler fashion. Dr. K. G. Larson, of Augustana College, Rock Island, U.S.A., discovered that when the rubber band is stretched it becomes positively charged. By stretching it over a bow-shaped wire he could give a charge of any size desired to an electroscope (devices for detecting the presence of static electricity) by running the band against the knob of the electroscope for a suitable distance. When the rubber band is allowed to return to its normal length it gives a negative charge when touched to the electroscope.
