Wash and dry your hair. The polarization experiment will not work with wet or greasy hair.
Comb through your dry hair several times to transfer electrons from your hair to the comb and give the comb a negative charge.
Hold the comb near a sheet of paper. The paper will move slightly away from the comb due to its negative charge.
Pull on a pair of socks.
Walk across a carpeted floor, rubbing your feet back and forth. This builds up a negative charge just as combing through your hair did in the previous experiment.
Touch a metal doorknob. The shock you feel is the result of the electrostatic charge created as the excess electrons on your body transfer to the doorknob.
