Juice cleaning pennies** What kind of juice cleans pennies best? I think orange juice, because it is the least stainless juice that I am using for this project. First, i am going to get the containers and fill them each up with a juice. Next, i wait 2 days, then I see which juice cleaned the pennies best. The materials that I am using are cran-apple juice, grape juice, apple juice, orange juice, 4 containers, and 4 pennies. First, i am going to get the containers and fill them each up with a juice. Next, i wait 2 days, then I see which juice cleaned the pennies best. experimental group= biology control group= juice independent group= The containers dependent group= the pennies and the juice

Why the gross stuff on pennies is on pennies, is because iron is on pennies, and iron attracts germs and other gross stuff. Copper comes from a sulfide ore called 'Chalcopyrite', which contains copper, combined with iron and sulfur. Another reason why it has gross stuff on it is because the penny is very old and rusted.
