Polishing Pennies

Polishing pennies was another perfect "P" activity for "P" week! We haven't polished pennies since O(5) was E's age (2), so it was time! O and I enjoyed looking at the pictures of her polishing the pennies before we began this activity.

First, E poured a half cup of white vinegar into a bowl. Then, she poured in 1 tablespoon of salt. She and O took turns stirring the mixture, and then they dropped in the pennies.

We made the mistake of leaving the pennies and other coins in the vinegar and salt solution for too long, and they turned green! Oops!
