Franklin's bells were a novelty in the 1600's. They were effectively detectors of p.d. or differences in charge density (hence voltage) between two surfaces. You can make one with a Coke can and a very high voltage supply which most physics labs will have. DO NOT TRY TO USE MAINS VOLTAGE. Tear off the ring pull tab and attach it to the + of a 50KV supply, dangling the insulated wire inside the can. Wind up the voltage. Depending on the elasticity of the wire, the ring-pull will be attracted to the (earthed) can and 'clang' As you wind the voltage up, it will clang more and more insistently.
