Electroscope - JavaLab

Using an electroscope, you can determine whether an object is charged or the polarity of the charge. When the (+) charged body is close to the metal plate, the metal foil's free electrons are attracted to the metal plate, and a positive charge is induced in the metal foil. The electric force unfolds metal foil.

Detection of Static Electricity - School for Champions

Electroscope. An electroscope is a device that detects static electricity by using thin metal or plastic leaves, which separate when charged. An object with a suspected static electric charge is brought near the metal plate or ball of the electroscope. Electrical charges move to the metal and down to the foil leaves, which then repel each other.

The reason this works is because when you rub your hands against a piece of material such as plastic or vinyl for example, electrons from your hands will get transferred to that material which means that the piece will become more negative (or negatively charged) and your hands will become more positive.

Gold-leaf Electroscope, Process to Detect and Measure Charge, If a charged body (for example, ebonite rod) is touched to the metal disc of the gold-leaf electroscope, the metal strips of the electroscope gets charged by conduction. They repel each other and open up. In this way, we can detect whether an object is charged or not.
