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!
WARNING!!! Pennies and vinegar make copper sulfite which is a poison that can be absorbed through the skin this is not safe yet I see it all the time please do NOT do this! Especially with old copper pennies!!ReplyDelete
