Pennies

The girls were happily playing upstairs on Saturday morning sorting the money from our change jar. The piles were sorted first by pennies and all the silver coins, and then the penny piled changed to shiny pennies and dirty pennies.

Walking by, I suggested to the girls that there was a way to change the "dirty pennies" back to shiny again- so we hopped on the Internet to find the "recipe".

The next hour or two involved the continual soaking of change in the vinegar solution, rinsing in warm water and drying the newly cleaned pennies.

The fun part, was the second half of the experiment where we got to change silver bits of hardware into the copper colour using the already used (yet still clear) vinegar solution.
