My Leiden Jar - the first electrical capacitor. Its basically a glass jar with aluminium foil wrapped on the inside and out of the jar, with a rod touching the inside of the jar and an insulated cap. The jar is charged up by a static machine, or similar, or in this case from a weak high voltage generator from one of my electrostatic loudspeakers. The charge stays for quite a while and can be dangerous so do be careful if your making one. Can kill!
