This year, I'm taking up a new challenge! I signed up to take a Machines and Tools class at my school and I can already say that it's really cool. My teacher Mr. G gave us a really interesting first assignment. He introduced my class to the invention of the first battery made out of copper and zinc!
Question: What's a penny battery?
Kelly: Basically it's a battery made out pennies!
