Fizzy Sensory Play

Do you have a little one who loves to get their hands dirty? If so, here is a fun opportunity to experiment with baking soda and vinegar to make a huge fizzy mess!  Watch for the reaction between the acid (vinegar) and base (baking soda) that produces the giant cloud of fizz and foam.

How we did it:

Materials List

  1. bowl
  2. flour (2 cups)
  3. baking soda (2 cups)
  4. vegetable oil (1/2 cup)
  5. food coloring - oil-based
  6. vinegar
  7. spray bottle
  8. straw
  9. spoon
  1. Mix the flour and baking soda in the tub or bowl. It's safe to use your hands!

  2. Measure a half cup of vegetable oil and use a straw to add a couple drops of food coloring to the oil. Mix well.  Note: the color will appear a lot darker in the oil than the final color when mixing with the dry ingredients.

  3. Add the colored oil to the bowl. Use a large spoon to mix the ingredients. Note: the food coloring may leave temporary stains on your hands, so use a mixing tool to avoid unwanted color on your hands.

  4. Play with the dough to form shapes or a scene! If you like, use cookie cutters or molds to help get you started.

  5. Fill a spray bottle with vinegar. Spray the dough gently and watch how the vinegar reacts to form fizz!
