The word "static" comes from the Greek word meaning "standing" or "stationary". Static charge is formed when electrons are added or removed from a material. The electrons that cause static charges remain in one location, thus the charge is not moving. Static charges can be easily produced in materials such as rubber, plastic, glass, and fur. In this demonstration, the fur tends to lose electrons and become positively charged, whereas the plastic tends to gain electrons and take on a negative charge. When the person holds the light bulb, he/she discharges and lights the bulb.
