Fizzling Monster Brains


  1. Plastic Cups
  2. Acrylic Craft Paint
  3. Wiggle eyes
  4. Buttons
  5. Sharpie
  6. Paint brush
  7. Gauze or Cheesecloth 
  8. Glue (I used hot glue)
  9. Misc. embellishments
  10. Baking soda
  11. Distilled White Vinegar
  12. Food coloring or liquid watercolor


  1. Have the kids paint their cups how ever they would like
  2. Add wiggle eyes, mouth, ect.. to the cups when the paint is dry
  3. Mix some coloring (liquid watercolors or food coloring) into a cup of vinegar
  4. Dump some colored vinegar into your monster cup
  5. Add your baking soda and watch the magic happen

NOTE: the amount of vinegar and baking soda does not really matter, we found best results if you do about a 4:1 ratio (4 parts vinegar to 1 part baking soda) and add the baking soda to the top of the vinegar for best results. However you can experiment to see what works best for you 🙂

NOTE: Always take caution when doing experiments with little kids. The items used are all fairly safe but need to be supervised by an adult.
