Leyden Jar, Convenient for many electrostatic demonstrations, Each

Details

Useful for performing various activities related to static electricity, this Leyden Jar comes with an inner and outer cup, as well as a plastic dielectric. The first device capable of storing an electric charge was the Leyden Jar, invented by German Ewald G. von Kleist on November 4, 1745. Von Kleist made the discovery accidentally while experimenting with electricity; he touched his electric generator to a nail stuck into a medicine bottle through the cork. Later, he received a great shock when touching the nail. Although he did not understand how it worked, he had discovered that the nail and the jar were capable of temporarily storing electrons - what we would today call a capacitor. Capacitors are used in every form of electronic equipment. This Leyden Jar is designed for classroom demonstrations and comes with durable inner and outer plates, a plastic dielectric, and instructions. The inner plate has a hook and ball attached, making it easy to charge. Use this equipment to duplicate many classic static electricity experiments. Learn about static electricity and the function of a dielectric with this unique device. The Leyden Jar is 3 inches in diameter and 8 inches tall.
