Supply List:
- Vinegar
- Baking Soda
- Paper
- Deep Tray
- Droppers
- Small Cups
- Food Coloring (choose your favorite colors)
- Paint (optional)
- Paintbrush (optional)
Instructions:
STEP 1. Fill three small cups halfway with vinegar and add 3-5 drops of food coloring to each cup. Mix well.
STEP 2. Cover the bottom of a deep tray with about 1/8 to 1/4 inches of baking soda.
STEP 3. Use droppers to add the colored vinegar to the baking soda in the tray.
TIP: Slightly oversaturate the baking soda with the vinegar to create a vibrant, fizzy reaction.
STEP 4. Make your print by placing a piece of paper onto the fizzy mixture. Press it down, and move it around to create unique patterns.
TIP: Allow the paper to sit on the baking soda and vinegar mixture for at least 30 seconds.
STEP 5. Peel the paper off and let it dry completely.
Optional! Once dry, use paint and a paintbrush to add stars and other celestial details to your galaxy.
Space Process Art
This space art project with fizzy reactions and galaxy themes is an excellent example of process art to explore with kids. Unlike traditional art, where the end result is planned, this activity focuses on the creative process. Kids get to experiment with vinegar, baking soda, and food coloring to observe how they interact and create unique patterns on paper.

Extend the Space Art Activity (Older Kids)
To make this fizzy galaxy art project appropriate for older kids, encourage them to expand upon their initial creations with more advanced artistic techniques and themes. For example…
- After the paper has dried, they can use paint, markers, and colored pencils to add intricate details, such as stars, planets, and nebulae, to enhance their galaxy scenes.
- Introduce the mixed media concept by incorporating glitter, metallic paints, and collage elements.
- Older kids can also research different galaxy types and try to replicate their features in their artwork. This extended project deepens their engagement with the theme and challenges them to think creatively and critically about the universe.
Space Art For STEAM
This fizzy space art activity is considered STEAM (Science, Technology, Engineering, Arts, and Mathematics) because it integrates scientific principles with artistic expression. Through the chemical reaction between vinegar (acid) and baking soda (base), kids observe and learn about basic chemistry concepts in a hands-on way.
They explore color mixing and absorption, which ties into principles of physics and material science. This activity encourages creativity and problem-solving as children experiment with different techniques to create their galaxy designs.
