|This electroscope is housed in a 250ml borosilicate glass flask
with a metal rod attached to a rubber stopper. A pair of aluminum
leaves are suspended from an alligator clip. The knob on top of
the rubber stopper accepts a charge. When the charge enters the
flask, the aluminum leaves separate.
The rod and alligator clip assembly is also available
separately for use with your own flask. Sold as a pack of three.
A package of six spare aluminum leaves can be ordered
