  You’re right, Geoff.

  Gold. On the periodic table of elements, Gold is represented by the number 79. Long ago, alchemists tried making Gold out of copper (number 29). If mercury (number 80) comes into contact with Gold, it will appear to be silver (number 47) for a while.

  You’re today’s winner.
