The structure of the electroscope

Observe and think

What do you see when you touch a glass rod rubbed with silk to the metal ball of an electroscope? Why does this happen?

How does an electroscope work?

When a charged object touches the metal ball of an uncharged electroscope, part of the charge is transferred to the metal foil of the electroscope, and the two metal foils open because they have the same charge and exclude each other. The more charge the charged object carries, the wider the angle at which the electroscope's metal foil opens.
