Insulators and Conductors Insulators - Charge cannot move Conductors - Charge moves freely - stays on outside Insulators Glass Wood Plastics (organics) Dry Air (10,000 V/inch) Vacuum Pure water Conductors Metals - sea of electrons Graphite Semiconductors Salt water Any ionic solutions Ionized air

Methods of charging Friction - greater/lesser affinity Conduction - actual transfer of electrons (demo) Induction - Charge just moves around (demo) Visa/Mastercard/Discover Demo Electroscope: Inductive/Conductive Grounding with Silk + plex fur + rubber Charge with VdG/induce Coronal with VdG Discharge:dosimeter/match Why there is an attraction? Vdg and water (Why is there attraction)
