Dirty Money Coin Activity - Great for President's Day (or any day)

We did a fun little project this weekend in relation to President's day, but you could do this anytime!  My son loves collecting coins, and throughout my Pinterest travels (ah, Pinterest, how I love thee), I saw a cute, easy project for us to do.

Dirty Money Coin Activity - Good for President's Day or Any Day!

  • 10 - 15 coins from your wallet
  • A plastic container
  • Water
  • Baking Soda
  • Vinegar (any kind)
  • Towel
  • Fill the tupperware container with water
  • Put in the coins
  • Add in a few shakes of baking soda
  • Pour in a few teaspoons of vinegar
  • An old toothbrush (if you have one!)
  • Go to work!
The great thing about this experiment is that it covers a lot good bases.  You can:
  • Observe the fizzing reaction when the vinegar meets the baking soda (kids love it!)
  • Sort the coins by oldest to newest, or type, or dirtiest to cleanest. 
  • Discuss how many people may have handled the coins, and what was going on in the year they were made.  My son loved seeing pennies older than I am!
  • Talk about the various presidents on the coins.

I'm not sure if our coins were substantially cleaner when we were done, but it was a really fun exercise.  We didn't use any specific measurements - mainly a bit of this and a bit of that for the vinegar and the baking soda, but it all worked out!
