• You can experiment with the electrostatic induction of conductors and the law of conservation of charge. Close the openings of the two pillow conductors so that the charged object is close to the ends of the conductors. When the pillow-shaped conductor is pulled apart at that time, one side is positively charged and the other is negatively charged due to electrostatic induction. When the conductors are brought into close contact again, both become uncharged. This confirms the law of conservation of charge.
