  • A child swoops down a plastic playground slide, his hair standing on end.
    Figure 9.1 Fig. 9.1 Static electricity from this plastic slide causes the child’s hair to stand on end. The sliding motion stripped electrons away from the child’s body, leaving an excess of positive charges, which repel each other along each strand of hair. (credit:)
