Static Electricity, 19th Century

Static electricity. Demonstrator holding a sheet of statically charged tissue paper, while using his other hand to induce a spark of electricity. Charging is achieved by rubbing the tissue paper so that electrons on the surface separate out. When a conductor (here, the other hand) is brought near to these loose electrons, a visible spark and shock occurs, sometimes accompanied by an audible crackle. Modern research on this topic began with Michael Faraday's 1832 experiments that showed it was a form of electric charge. Artwork from the first volume (first period of 1888) of the French popular science weekly 'La Science Illustree'.
