Penny Lab

The penny lab was an interesting lab. It was fun to work with fire to change the penny's color. I thought it was kind of strange that a penny's color could change but then I realized that of course, the penny was just coated with the grey chemical and the fire reacted with the chemical to change the color. I really liked the penny lab even though my penny's color didn't fully change to gold. I was hoping it would but there's always next time.
