Electroscope (conductor): Place one or two of these conductors anywhere on the Lab Bench. You can attach flags and a neon bulb to this conductor (see figure below). In the conductor's Properties Box, you can set its charge. You can also show or not show the Model View and the Microscopic View of the electroscope.

An electroscope can exchange charge with a pendulum ball or another electroscope through direct contact or by way of a neon bulb. An insulator can transfer charge to an electroscope through rubbing. However, the electroscope cannot transfer charge to an insulator.
