I am doing a science project about which juice cleans pennies best. I tried lemon, orange, and apple juice. I did three trials of my experiment. On average, the orange juice cleaned the pennies much better than the lemon or apple juice. My research shows that lemon juice should have been best. Do you know why this might have happened?
