Picture of Turn Copper Pennies Gold and Silver Pennies!
In this experiment you take well cleaned pennies and turn them into pennies that are gold and silver! Extraordinary! However this experiment requires chemicals that are approximately $8-$10 and you need two of these chemicals. However, some of the materials you may not have such as a hot plate are a bit costly, and when I mean costly I mean like $300! When you have your result it should look completely different and unique so please continue with this experiment!

Step 1: The Materials!

Picture of The Materials!

These materials are chemicals that you can find at chemistry stores and some of these materials are everyday items. They are:

-Two small beakers(50ml, and 250ml)
-Hot Plate
-Tweezers
-Zinc Sulfate, 100g
-Zinc Metal, Mossy, 100g
-Glass Stir Rod
-Tap Water
-Copper Pennies, Well Cleaned

Step 2: How To Start Making Silver Pennies!

What you do for making silver pennies is fairly easy like making the golden pennies which is next!

Fill the small 50 mL beaker with 3/4 full tap water. This is your rinsing beaker. Set aside.
Dissolve 30 grams of Zinc Sulfate in 100 mL of water in the 250 mL beaker. A little heat from setting on the hot plate will hasten this dissolve.
Silver penny turning
Place mossy zinc pieces in the beaker with the zinc sulfate solution, enough pieces to almost cover beaker bottom.
Using tweezers, place two or three cleaned up pennies in step three beaker making sure pennies touch the mossy zinc pieces and are not touching each other.
Bring solution to low boil for about 10 minutes. Your pennies will slowly turn a silver color.
Using tweezers, carefully remove the pennies from the solution, rinse and cool them in small wash beaker then dry them on a paper towel.
Voila! You now have a dandy silver colored penny.

is real gold?

Why would you need a $ 300 hotplate to do this, a kitchen electric stove hotplate will do the job.

True, I should edit that.
