We mixed up a paste with: cornstarch, food coloring, and water
(easy peasy lemon squeezy)
I used my trusty muffin tin as our palette.
The colors were so vivid!
We had a great time.
Helpful Tips if you try this at home:
1. I mixed the cornstarch and food coloring first inside the house.
We carried the muffin pan with the dry powder outdoors,
THEN added the water with a small watering can
(to control splashing)
This way we didn't slosh and stain the house on our way outdoors!
2. Make sure you use a good ratio of cornstarch to water.
You'll want it to be a thicker paste not too watery so the color will show up.
