O and I shined pennies this morning. It was fun, quick, easy, and educational! If you do this activity with a child under age 3, please be very careful since pennies are choking hazards for kids who still put thing in their mouths. First, we mixed a 1/2 cup of white vinegar and a tablespoon of salt and stirred it up. O usually holds the measuring apparatus while I pour in the ingredients, then she pours them into the bowl.
Dropping the pennies into the vinegar and salt mixture.
Drying the pennies and admiring their shininess.
Here are our clean and shiny pennies! They actually don't look that great in the picture, but they are MUCH prettier than they were before we started. We also dropped a few quarters, nickels, and dimes into the mixture and talked about how the chemical reaction that cleans them only works with copper. That's probably over the head of a 2 year old, but I thought it was good to expose her to new information :)
