Materials
- Baking soda, common and easy to find.
- White vinegar or clear vinegar, easy to pour.
- Small cups or shallow dishes, one per fireworks burst.
- Food coloring or liquid watercolors, optional for gentle color.
- Pipettes, droppers, or teaspoons for controlled pouring.
- A tray or washable mat to catch spills, optional but helpful.
- A clear workspace and a bowl of warm soapy water for cleanup.
Instructions
- Arrange your workspace with a tray and cups. Place cups on the tray so you can move them without spills. Set colors and droppers nearby for calm reach.
- Add baking soda to each cup. Spoon in a gentle mound, noticing the powder’s fine texture. Press lightly with the back of the spoon to level it.
- Mix small amounts of vinegar with color. In a separate container, add one drop or two of food coloring to a small amount of vinegar. Stir slowly and watch how the liquid takes color.
- Use a droplet tool to add the colored vinegar. Hold the pipette close to the baking soda. Let droplets fall slowly and count the fizzing sounds together.
- Observe the foam rising and the colors spreading. Lean in to notice how bubbles reflect light differently. Take a soft breath and name the sensations you see.
- Repeat with small changes. Try a different color or a slightly larger drop. Pause between bursts to let the surface settle and to notice changes.
- Clean up gently as you go. Wipe spills with a damp cloth and rinse cups in warm soapy water. Talk through each step as you tidy to keep the pace thoughtful.
- Reflect on what you saw. Compare which color made the tallest foam or which cup fizzed longer. Record a note or small sketch if you like to remember the moment.
