Monday we started an experiment. Can you clean a penny with salt and vinegar. Working together to follow directions we rubbed some salt on the pennies. Nothing. Then rubbed some vinegar on the pennies. That sort of cleaned some of them. Then we put them in a jar of both ingredients mixed together. We were supposed to take them out of the jar at the end of the day but we are a curious lot and so we waited till Friday.
Well it was. Nice work everyone.
Five days later...some of the pennies looked like this. Nice and clean, not so shiny though.
