Yesterday, 8/19, our chem class turned a penny gold. First we put our pennies in a zinc solution and then let it set in it. After the penny was completly silver from the zinc, we used a bunsent burner. We took a tongs and held the penny under the bunsent burner. The zinc truned the penny gold under the high heat. It was really cool. After putting it under high heat we placed it cool water to cool it down and the cleaned it up. We have a shiny gold penny!
