This activity kept my kids happy and playing for well over half an hour! It was so easy to set-up. All we needed was some white vinegar, a couple tablespoons of salt and some coins. For my sanity, we used a few bowls and towels as well to contain the mess.

First the kids dipped their rags into the vinegar and salt, then they scrubbed the coins. It was fun to watch the acid from the vinegar remove the dirt, grime and corrosion – those pennies really began to shine! The kids were curious as to why the dishrags were turning green and we had fun discussing how metals like copper break down and their rust is a bright blue/green.
