Today for our Artsy Wednesdays we tried another art and science experiment, a colorful acid-base chemical reaction painting.
We used the interaction of colored vinegar and sodium bicarbonate to create a chemical reaction that resulted in a rainbow of colors. FriBoy, who is 6 by the way, thought this was magical and I love this attitude to science projects because I think in time it will keep the flame of curiosity and wonder burning. Science is magical!
Here is what we used:
- Baking soda
- Food coloring
- A white canvas or watercolor paper
- Small goblets to mix the stuff (I used our eau de vie glasses :)), bottle caps could also do
Fill each goblet/cap with vinegar, add a few drops of the food coloring. Mix the colors any way you want.
Place them on the white canvas or watercolor paper and add 1/2 teaspoon of baking soda to each goblet and watch the reaction and how the colors mix.
This is a very messy experiment, I don’t mind the mess but if you do, it’s better to do it in a controlled environment: use protection for the table and set up the quantities the child can use from the beginning.
