Ingredients Method Notes

Ingredients
  

  • Baking soda 1-2 tablespoons per jar
  • White vinegar plain or diluted, optional food coloring
  • Small glass jars clear cups, or shallow dishes
  • Food coloring or liquid watercolors optional
  • Droppers pipettes, or small spoons
  • A shallow tray or washable surface to catch spills
  • Measuring spoons optional
  • A paper towel or small cloth for drying

Method
 

  1. Choose a calm space and set your tray or shallow dish on a flat surface. Arrange jars with a gentle distance between them.
  2. Take a slow breath and feel the table beneath your palms.
  3. Add baking soda to each jar using a small scoop or measuring spoon.
  4. Notice the soft, powdery texture as it settles like pale snow.
  5. If you want color, add one or two drops of food coloring to the baking soda.
  6. Fill a squeeze bottle or cup with vinegar and tint it, if desired.
  7. Use a dropper to place a small amount of vinegar on the baking soda.
  8. Listen for the fizzing sound and observe the reaction.
  9. Try a steady, thin stream of vinegar for lace-like foam, or a small pour for bursts.
  10. Pause between pours to breathe and observe the changes.
  11. If foam spills, let it settle and gently wipe with a soft cloth.
  12. Experiment with adding multiple colors for layered reactions.
  13. When finished, pour the mixture down the sink and rinse jars with warm water.
