How to Clean a Penny...

Part of our Disney fun was making those souvenir pennies so we wanted to make sure they were nice and shiny. We decided to make it a science experiment. We searched through our pennies and found equally dirty ones so they'd start on equal footing. We tried cleaning pennies in Salt, vinegar, mustard, ketchup and milk. First, we all predicted which one we thought would clean the best. Which one do you think would?

Nothing beats messy science!

They loved this and wanted to keep trying more and more things from around the house!

Can you tell which one got it the shiniest?

I predicted vinegar, but it was in fact ketchup! How cool is that? Of course, it has vinegar in it and also the acid from tomatoes. We all thought that was too cool!

I SO need to do more experiments like this...
