Previous Next Lord Kelvin's Waterdrop Experiment # 5A40.70
Description: This unit allows you to easily recreate Lord Kelvin's famous electrostatics experiment, in which an electrical current is induced by the breaking apart of water droplets. As the potential increases to 100V+, students observe an electrometer scale on the overhead projector. Setup Time: 1 day Quant. in Demo Room: 1 Demo References The Video Encyclopedia of Physics Demonstrations Disc 17-05 A Kelvin water dropper discharges a small neon lamp. Animation sequence shows principles of operation. Sutton E-25 A diagram and some construction details are given for the Kelvin water dropper. A "dry water dropper" using steel balls is mentioned. Meiners 29-1.23 Explanation of and directions for building a Kelvin water dropper. Picture, construction details in appendix, p.1311. Meiners 29-1.24 A simple Kelvin water dropper made with shower heads enclosed in cans. Diagram. Freier and Anderson Ea-14 Sparks are produced by water falling through two rings connected by an "x" arrangement to opposite receivers.
