All about Static Electricity
Static electricity builds up when electrons move from one material to another, often through rubbing. The object then holds an electric charge that can attract light objects or give a small shock.
Lightning is a very large example of static electricity discharging through the air.
Static electricity is a build-up of electric charge on the surface of an object. It happens when electrons move from one object to another, often when two materials rub together. A balloon rubbed on your hair picks up electrons from your hair, so it becomes negatively charged.
