Which Rod Takes Which Charge
Rubbing moves electrons from one surface to the other; it does not create charge. Glass rubbed with silk loses electrons and becomes positive, leaving the silk negative. Ebonite rubbed with fur gains electrons from the fur and becomes negative. Hang the charged ebonite rod in a paper stirrup on a thread and bring the rubbed glass rod near: the ebonite swings towards it, because unlike charges attract. To show repulsion, touch one charged rod to two pith balls or to the cap of an electroscope, so that both pick up the same charge and push apart.
Getting Clear Results
Charging works poorly in damp air, so keep the rods and cloths dry and, if needed, warm the glass rod gently first. Rub briskly along the rod, hold each rod by one end only, and avoid touching the charged part, which lets the charge leak away through the hand.
