ECSTATIC STATIC  | Urdu

You can demonstrate Static Electricity using the strands from an old plastic sack. You need 20-30 strands, about 50-cms long. Tie the ends of these strands together. Hang this bunch vertically and then rub them very quickly with your fingers. The strands rubbing against each other will acquire a charge. The strands repel each other and they fluff up. If you bring your hand close by the strands will be attracted to your hand. On a hot dry day the charge on the strands remains for a fairly long time. During the rainy season the charge leaks off fast. For discharging the strands hold the bunch and wrap them on your hand. Once again flick them quickly with your hands and the strands will acquire a charge and spread out.
