Inflate a balloon and tie a knot. Bring it close to your hair and head and nothing would happen. Now rub the balloon on your hair. This will knock down a few electrons and the balloon will get electrically charged. On bringing the charged balloon near your head your hair will be attracted to the balloon and will stand upright!! It is a wonderful sight to behold and the feel the power of static electricity!! Finally you can place the balloon on your head and it will be attracted to your hair. The balloon will stick to your hair!! This experiment works best on a cold, dry day. On a moist, rainy day the charge leaks off very fast.
