Build a simple electrochemical cell using orange juice and copper and magnesium metal. The resulting spontaneous oxidation– reduction reaction will generate enough electricity to power a battery-operated clock. What makes the clock work? How long will the clock run? What happens if the metals are reversed? Use this demonstration to promote inquiry, inspire wonder, and highlight the process of scientific discovery.
