4. Rainbow Eruptions
This activity requires a few household items. You’ll need water, baking soda, vinegar, food coloring or liquid watercolor paint, squeeze bottles (which I’ve heard can be bought at Walmart for $1 a piece) and cups to make your art in. Pour a small amount of food coloring or watercolor paint into your art cup and cover with a large tablespoon of baking soda. Fill your squeeze bottle with vinegar and then have the kids go to town spraying the vinegar into the cups!
You can find the full tutorial, including the non-vinegar recipe at LearnPlayImagine.com.
