Pie Plate Electrostatics Plexiglas is an insulator. Normally, it is electrically neutral with equal numbers of electrons (negative charges) and protons (positive charges). Electrons can be placed on or removed from an insulator, but they will stay put; they cannot move around easily. Large numbers of electrons can be rubbed off the Plexiglas using quick, vigorous strokes with the felt cloth. This leaves a net positive charge on the Plexiglas, and a net negative charge on the felt (also an insulator). You can neutralize the felt by rubbing it slowly against a grounded, metallic outlet plate. The aluminum pie plate is a good conductor. Normally it is neutral. Electrons can be removed from or added to a conductor and can move freely within the metal. The electrons will move to locations governed by their attraction to positive charge and repulsion from negative charge. Due to the salts and fluids in its cells, your body is a good conductor. Thus, electrons travel freely through your body. It is also large and thus a reservoir of charge, meaning it can give or
