What to Do:1. Place your cauldron on your cookie sheet or plate. Add about 1 tablespoon of baking soda to the bottom of your cauldron or cup. 2. Add a few drops of food coloring to the baking soda in the cauldron. 3. Fill your spoon or eye dropper with vinegar. 4. Drop a few drops of vinegar into the cauldron. Add more vinegar for a faster and larger chemical reaction. 5. Watch the potion bubble over! Why Does It do This? The classic baking soda and vinegar experiment is called an acid/base reaction. Vinegar is an acid and baking soda is a base. The bubbles that are created are carbon dioxide being released from the reaction. Learn more about it here. Check out our Instagram reel of this!
