Electrostatic charges are indicated by the deflection of a black plastic straw pivoted on a pin. The polished zinc plate on top is used to demonstrate photoelectric effect and various other electrostatic demonstrations. The metal case measures 14 cm in diameter. The scale is graduated in 10° increments in two quadrants.

Pith balls are an electrostatic necessity.

Demonstrates static potentials.

Used to Detect Electrostatic Charge

Spare pith balls for pith ball electroscope.

Six aluminum replacement leaves for the Electroscope Assembly without Flask.

A Highly Sensitive Electroscope

Simple, timeless demonstration of electrostatics.

Obtain quantitative data for electrostatic experiments

A thin aluminum coating produces great sensitivity to electrostatic charges. Styrofoam pith-like balls measure 8 mm in diameter and each has a silk suspension cord.
