🎨 Baking Soda Painting (Fizzing Art Project)
Materials Needed:
-
Baking soda (about ½ cup)
-
Water
-
Food coloring or liquid watercolors
-
Small bowls or muffin tin (for color mixing)
-
Paintbrushes or droppers
-
White cardstock or watercolor paper (thick paper works best)
-
Vinegar
-
Pipettes, droppers, or small spoon
-
Tray or newspaper (to contain the mess)
🧪 Instructions:
1. Make the Paint:
-
In each bowl, mix:
-
1 tablespoon of baking soda
-
A few drops of food coloring or liquid watercolor
-
A splash of water (just enough to make a paste)
-
2. Paint Your Design:
-
Use a paintbrush or spoon to apply the baking soda paste to your paper in any design or pattern.
-
You can let kids get creative with abstract art, shapes, or even spelling their names.
3. Time to Fizz!
-
Once the painting is dry or partially dry, use a dropper or spoon to gently drop vinegar onto the painted areas.
-
Watch the fizzing chemical reaction as the baking soda and vinegar combine — it bubbles and foams, spreading the colors and creating cool effects.
4. Let It Dry:
-
After the fizzing settles, let the artwork dry flat. It will leave behind colorful patterns and a textured, almost tie-dye look.
💡 Tips & Variations:
-
Add glitter to the paint mixture for sparkle.
-
Try using stencils for shapes or letters.
-
Use this as a STEAM lesson: explain the acid-base reaction (baking soda = base, vinegar = acid).
-
For younger kids, pre-mix the paints and just let them drop vinegar for a fun, sensory fizzing experience.
