Watch as your finger mysteriously moves a pencil without touching it!
Wiping your feet on the carpet generates a static charge on the surface of your body. Electrons eventually spread out over your entire body. Moisture in your skin creates pathways for the flow of electrons. The pencil has no charge, but its neutral state is positive when compared to the negatively charged electrons on the surface of your skin. This difference in charge is enough to cause the pencil to move.
