One thing used in the seventeenth and eighteenth century to study static electricity was the Leyden jar. This device consisted of 2 conductors separated by an insulator, usually tin foil on either side of a piece of plastic or glass. It is used by being charged by a static generator. The electricity flows into the jar and stays there. After being charged, a person can connect the conductors, causing a spark and the charges to discharge, resulting in the jar to be neutralized.
Another thing used to study static electricity is the Wimshurts machine. This decive is an electrostatic generator that has rotating disks with metal carriers in them. When used, the charges are produced by induction.
