A pith ball is typically made of a lightweight material called pith, which is soft and spongy tissue found in the stems of certain plants like the common rush or the elderberry. This material is ideal for static electricity experiments because it is light enough to be easily manipulated by electrical forces.
The 'charge' in the pith ball is actually caused by too many or too little electrons. When you touch the ball, these billions of electrons would rather move to your nice, moist skin, than stay in the dry pith ball, because your skin is a better conductor than pith is.
Lightweight pith balls help to show electrostatic attraction and repulsion.A pith ball picks up electric charge.
When you move the ebonite rod closer to the pith ball, the pith ball becomes negatively charged due to the transfer of electrons from the rod to the ball (inducing a positive charge on the rod). When you move the rod away, the pith ball returns to its neutral state as the charges redistribute.
There are two main types of electroscopes: gold-leaf electroscope and pith-ball electroscope. Gold-leaf electroscope uses thin gold leaves to detect electric charges, while pith-ball electroscope uses lightweight balls made of pith or other materials that can be attracted or repelled by electric charges.
The initial charge on a pith ball is typically neutral, meaning it does not have a net positive or negative charge. It can be charged by bringing a charged object near it, inducing a separation of charges within the pith ball.
The pith ball will have a negative charge after touching the negatively charged polyethylene strip. This is because electrons are transferred from the strip to the pith ball, leaving the pith ball with a net negative charge.

When the glass rod is rubbed with a cloth, it acquires a positive charge by gaining electrons. When the charged glass rod is brought close to the pith ball, the negative charges in the pith ball are repelled, causing the pith ball to become positively charged by induction.
Assuming the pith ball is uncharged, and the rod isn't touching it: The electron particles on the fur will have come off on the rod, giving it a negative charge. As a result, the pith ball will be attracted to the rod because all uncharged matter is attracted to charge matter.
You could use the pith ball electroscope to test different materials by charging it with the materials and observing the behavior of the pith ball. If the pith ball is deflected more when charged with a particular material, it indicates that the material holds onto its electrons more strongly.
The pith ball will be attracted to the plastic rod because the rod acquires a negative charge when rubbed with silk. This causes the pith ball, which is neutral, to be attracted to the rod due to the opposite charges.
You can charge each material by rubbing it with a cloth to transfer electrons. Then, bring each material close to the pith ball electroscope without touching it. The material that causes the pith ball to deflect more significantly is the one that holds on to its electrons more strongly.
