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' | |
