This was our first year to do a Science Project. Gabby decided she wanted to see which juices cleaned pennies the best. We had all sorts of Juices: Pineapple, orange, coke, apple, cranberry, pickle juice, vinegar,grape, water, soapy water. We decided that baby food jars would work best. So my grandma took Gabby to the store and they bought baby food. It was mostly applesauce and the kids loved eating it. She then put the juices in and soaked pennies for a few days.
The results were that pineapple juice cleaned the pennies the best.
