Ingredients

For the Baking Soda Pastel Growing Tree

1 cup baking soda
1/2 cup water add gradually as needed
1/4 cup white vinegar
food coloring pastel colors of your choice
cardboard for the tree base

Equipment

Mixing bowl
Spoon
Small Cups or Bowls
Baking tray

Method

Step 1: Combine 1 cup of baking soda with 1/2 cup of water in a mixing bowl. Stir until the mixture becomes smooth and slightly thick. Add water gradually and adjust the consistency as needed so it can hold its shape.
Step 2: Place the cardboard base on a baking tray or protected surface. Use your hands to shape the baking soda mixture into a sturdy tree trunk and several branches.
Step 3: Divide 1/4 cup of white vinegar among several small cups or bowls. Add a few drops of different pastel food coloring shades to each portion and stir gently until evenly mixed.
Step 4: Carefully pour the colored vinegar over different parts of the baking soda tree. Watch as the mixture fizzes and bubbles, creating colorful patterns across the trunk and branches.
Step 5: Leave the finished tree undisturbed and allow it to dry overnight. Make sure the structure feels firm and completely dry before moving or decorating it.

Notes

Experiment with pastel colors, branch shapes, and different types of vinegar. Liquid watercolor or suitable natural dyes can replace food coloring. The reaction can overflow, so use a baking tray or protected surface. Adult supervision is recommended, especially when children are participating.
