No reviews

A fun, hands-on kitchen science activity where kids can grow crystals on a tree made from pipe cleaners or twigs using baking soda.

Ingredients

  • Baking soda (sodium bicarbonate)
  • Warm water
  • Table salt (optional)
  • A shallow glass dish or small jar
  • A small glass or plastic cup for mixing
  • A spoon for stirring
  • Pipe cleaners or a small twig (optional)
  • Food coloring or liquid watercolor (optional)
  • Tweezers or a toothpick (optional)

Instructions

  1. Prepare a calm space and gather all materials. Keep the surface clean and lay a towel down.
  2. Warm the water to a comfortable heat, avoiding boiling.
  3. Measure and pour baking soda into the mixing cup, starting with about 2-3 tablespoons for a cup of water.
  4. Slowly add warm water and stir to dissolve until the solution looks clear.
  5. If desired, add a pinch of salt or a drop of color.
  6. Shape your tree in the shallow dish or jar using pipe cleaners or a twig, ensuring it is anchored in the solution.
  7. Pour the baking soda solution around the base of the tree.
  8. Wait and watch for initial crystals to form, checking every 15-30 minutes.
  9. Make gentle adjustments with tweezers as necessary.
  10. Let the piece sit undisturbed for several hours for crystals to grow thicker.
  11. Once satisfied with the crystals, remove and let dry, or keep in the dish for longer observation.

Notes

Adult supervision is recommended for young kids. Cleanup is minimal; baking soda brushes off easily with water.
