EST-30 GOLD LEAF ELECTROSCOPE, SIMPLE FLASK TYPE

It consists of very thin leaves of gold hanging from a metal stem with a metal disc at the top.

The leaves are protected by a 500ml conical glass flask with a rubber stopper and an insulating bushing.

If an electric charge is applied to the metal disc, the charge distributes itself over the top, stem and leaves, charging both leaves with electricity of the same kind, and causing them to repel each another.

The flask is provided with a wide foil earthing strip which runs down diametrically opposite sides and across the bottom.
