Charge Polarity June 19, 2017
Reviewer: walter clark from Fullerton, CA United States  
The Ebonite rod charges minus.
A glass test tube charges plus.
But that is only with some kinds of rubbing cloth.
It is really useful to find the right combination of cloth and solid object material to have both plus and minus. (Which can be revealed with an electrometer.)
