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 cup baking soda
- ½ cup white vinegar
- food coloring
- small baking sheet, or pie pan
- eye dropper, pipette, or straw
-
Step 1
Assemble your ingredients.
-
Step 2
Cover your baking sheet or pie pan with an even layer of baking soda.
-
Squeeze drops of food coloring onto the baking soda.
-
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?
