Which juice Cleans Pennies the best?
By Tomas Edison
For my Science fair Project this year, I chose an easy project, my hypothesis was correct! Grape juice clean pennies the best. I used three types of juice. The three juices were apple, orange and grape juice.
This project was a success, and it was easy to work on. The acids in the juice are different and the three juices have different amount of sugar and they have different molecules.
