DIY Ombre Penny Art
A fun science experiment to do with kids!
You probably already have what you will need:
Burlap or canvas as backing
Vinegar and salt
Start with the frame.
(I spray painted my gold frame with a little
copper and teal...just for fun!)
Wrap burlap on the backboard, remove the glass
and hot glue it in the frame.
See how many pennies fit in the space.
96 for me.
(my 4th grader did the math)
Get a bunch of pennies!
They are naturally a wide range of colors...
Sort out the brightest, brownest,
blackest, whitest and teal-est ones.
Now, the science.
Take some mid-range colored pennies
and put them in a glass dish.
Add 1/4 cup white vinegar and 1 teaspoon of salt.
Immediately they will brighten and become shiny.
Let them soak about 5-10 minutes.
Pull them out and set them on a plastic plate...
don't dry them off...
Over the next 2 hours they become slimy looking
and turn very bright turquoise--or verdigris as it is called.
Our pennies dried over night.
Arranged them on the burlap.
I let the kids decide which were brighter and didn't
care too much if they weren't exactly so.
Then hot glue them onto the burlap!
