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!
Cover your baking sheet or pie pan with an even layer of baking soda.
Squeeze drops of food coloring onto the baking soda.
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?
