We love things that fizz AND we love watercolors, so of course we needed to combine these loves to see what would happen! I mixed up a set of four colors based on S's request. Because the paints had a tendency to settle after a few minutes and we were painting for awhile, I left spoons in each color to make it easy for S to remix if needed. I set all the paints inside a pan to prevent any accidental spills. :)
S dove in and we both marveled at the thick sparkly paints. The colors were so vibrant and S experimented with alternately mounding the paint and spreading it thinly.
A better view of the incredible texture of the paints.
A close up. So pretty! They remind me of thick acrylic paints.
We tried spraying vinegar - and it *sounded* cool, but you couldn't see much bubbling at all. Next we tried adding vinegar with an eyedropper and that had much more dramatic results.

We let the paintings dry overnight on a flat cookie sheet. The next morning we were so surprised - don't they look like moonscapes? Super cool. The once vibrant colors faded to more of a pastel, but the baking soda had created all of these amazing craters and mountains. This top photo is of the painting we sprayed vinegar on (using a spray bottle).
This lower painting was the painting where we added vinegar with an eyedropper.
To make your own fizzing watercolors, you will need:
Liquid watercolors or slightly diluted food coloring
Baking Soda
Vinegar
Watercolor Paper
Add a tablespoon of baking soda to a cup (do this for each color you'd like to make). Add just enough liquid watercolor or dilute food coloring to cover the baking soda. Stir well. The paint should have the consistency of tempera paint. If it is too runny, add more baking soda; if it is too thick, add more liquid watercolor or dilute food coloring. The paint will separate if left for several minutes - we found keeping spoons handy helped.
Paint your picture on watercolor paper. When you've completed the picture, move it to a tray or cookie sheet with an edge (to contain any overflowing liquid) add vinegar (see above for the two methods we used - or try another method!) and enjoy the fizzing. We added just enough liquid to react all the baking soda (not so much that the paper was floating in a pool of vinegar). Allow the paintings to dry for 24 hours to see the final results!
