Gold Leaf Electroscope, 1 Each

The Gold Leaf Electroscope by United Scientific detects the presence of electric charge using gold and aluminum leaves inside a metal case with front and rear glass windows that block air currents. The leaf support rod is insulated by a plastic sleeve, and a graduated scale reads deflection from 0 to 90 degrees. Physics teachers use it for electrostatics demonstrations of charging by contact and induction, with an activity guide included.
