This TeacherGeek Mini Hub is designed to slide directly on a motor shaft. It is comprised of two parts that are held together with a single screw. This allows you to secure 2, 3 or 6 turbine blades. When the hub is mounted on the motor shaft and driven by the wind, electricity is generated.

This extra large electroscope is ideal for classroom demonstrations of electrostatic principles. A lightweight metal vane is used as a pointer in the electroscope. This lightweight metal blade deflects when the electroscope plate is charged. A transparent scale is provided to measure the angle of the deflection. Front glass window slides up to allow insertion of ionizing material in chamber.
