Glass Jar or Glass ... An electroscope is an instrument for detecting the presence of static electricity. It consists of two thin metal leaves suspended from a metal hook. ... When the hook is brought near a source of static electricity, some of the electrons in the hook are pushed to the leaves (if the source is negative)

Here is the basic gold-leaf electroscope. Two thin gold leaves are suspended from the bottom of the brass top of the glass cylinder, and connected to the sphere at the top. ... The 1888 Queen catalogue lists it as a "Plain gold Leaf Electrometer" and prices it at $3.75. Note that it is not an electrometer, but an electroscope;

To test the Electroscope, create some static electricity. An easy way to create static is by rubbing a balloon on a Styrofoam plate. When you do this, you "charge" the plate, which means you cause a buildup of electrons on one side.

Inventors of electroscope: ... Nollet invented one of the first electrometers in 1748, the electroscope, which showed the presence of electric charge by using electrostatic attraction and repulsion. ... When the positively-charged electroscope is touched, its charge becomes grounded (or neutralized). This is depicted in...
