Cleaning Pennies

Written by Mommy Cameron | Homeschooling

There have been several times that the boys have complained about the smell of vinegar when I clean, however, they don’t complain as much as Daddy Cameron.  Thus I thought it would be good to show the boys the cleaning power of vinegar.

Directions:
1.  We began by talking about the different ways to clean things.  Thing 2 mentioned water.  Shortly after Thing 1 mentioned soap and water.  I then introduced the vinegar, which they immediately recognized from the smell.

2.  I then let each boy set up one cup.  Thing 3 set up the water cup and dropped his pennies in.  Thing 1 set up the soap and water cup.  Thing 2 set up the cup with 1/2 cup of vinegar and 1 tsp of salt.

3. We then let the cup sit for about 15 minutes.

When we looked at the pennies after 15 minutes, Thing 1 immediately wanted to change his hypothesis from soap and water to the vinegar.  The pennies in the vinegar and salt solution were pretty shiny.

This was a great visible example of why I use vinegar to clean our house.

Have you ever cleaned pennies?
