Science Story Time Experiment: Fizzing Planets

What You Will Need

  • Vinegar
  • Baking Soda
  • 2 Colors of Food Coloring
  • 2 Bowls
  • 1 Tablespoon
  • 1/4 Cup
  • Spoon or Dropper
  • Gloves
  • Water

Instructions

Blue and green ball of baking soda mixture fizzing.
  1. Add ¼ cup of baking soda to each of your bowls.
  2. Add 1 tablespoon of water to each of your bowls.
  3. Add one drop of food coloring to each of your bowls (each bowl should be holding a different color).
  4. Mix together. If your mixture seems too watery, add another tablespoon of baking soda.
  5. While wearing gloves to avoid staining your hands, mold your two baking soda mixtures together to form a round planet shape.
  6. Set your planet into one of your now empty bowls and slowly add vinegar to it using a spoon or dropper.
  7. Observe!

Science Behind It

You can see that as you added your vinegar to your baking soda planet, the planet started to dissolve! The more vinegar you add, the more your planet will dissolve and get smaller! So why does this happen? Baking soda acts as a base and vinegar acts as an acid. When they combine, they create carbon dioxide gas, which gives us our fizzing bubbles!
