1) Measure out 1/4 cup white vinegar and put into the glass bowl.
2) Add 1 teaspoon salt. Stir salt until it dissolves in the vinegar.
3) Take a penny and submerge it into the vinegar solution 1/2 way for 10 seconds.
4) Remove penny. What do you notice? What do you think happened?
5) Put all the pennies into the bowl and let them sit in the white vinegar solution for 5-10 minutes (take notice of how the pennies look before putting them in).
6) Take pennies out and put them on a paper towel after step 5.
7) Put one steel nail into the bowl and let it sit all the way on the bottom fully submerged.
Take another steel nail and lean it up against the side of the bowl so it's 1/2 way in the
vinegar
