Jake a used ballpen refill and rub it vigorously with a piece of polythene. Bring it close to small pieces of paper. Take care not to touch the rubbed end of the refill with your hand or with a metallic object. Repeat the activity with small pieces of dry leaf, husk and mustard seeds. Record your observations.

When we rub ballpen refill with polythene, it acquires a small electric charge. On bringing the charged ballpen refill close to small pieces of paper, the bits of paper are attracted to it. A charged plastic refill can attract bits of paper.
