Touch a metal doorknob. The negative charge on your hand pushes away electrons on the surface of the doorknob.  The surface of the doorknob then has a positive charge.  Electrons may jump from your hand to the doorknob.  You feel a mild shock or tingling. You may also see a spark of light. What is this called?

• gravity

• The electric slide

• electric discharge

• static electricity
