Fizzing Colors!

Fizzing Colors!

Turn your kitchen into a chemistry lab with this simple science experiment! You only need three ingredients: baking soda, food coloring, and vinegar. When you combine the ingredients, a chemical reaction occurs and results in a bubbling eruption of fizzing color. Acids – like vinegar – and bases – like baking soda – are special kinds of chemicals that tend to react with each other to form something completely new: carbon dioxide gas. So the bubbles you see are filled with carbon dioxide gas which creates all the foamy fizz!

How we did it:

Materials List

  1. 1 cup baking soda
  2. ½ cup white vinegar
  3. food coloring
  4. small baking sheet, or pie pan
  5. eye dropper, pipette, or straw
  1. Step 1

     Assemble your ingredients.

  2. Step 2

    Cover your baking sheet or pie pan with an even layer of baking soda.

  3. Squeeze drops of food coloring onto the baking soda.

  4. Step 4

    Use an eye dropper, pipette, or a straw to drip vinegar on top of each color drop. And voila – chemistry at work! Experiment by adding more color or vinegar. How many bubbly eruptions can you make at once?
