Everyone knows the baking soda and vinegar volcano, but there are so many other cool chemistry with baking soda and vinegar experiments. I've done the balloon inflation and the rocket, but what other creative uses have you found for this classic combination in your kitchen pantry science projects?
One of my favorite chemistry with baking soda and vinegar experiments is making homemade fire extinguishers. You put vinegar in a small bottle, baking soda in a tissue, then attach the tissue to the bottle cap. When you shake it and point it at a candle (safely!), the CO2 puts out the flame. Great demonstration of gas production and fire safety.
For kitchen pantry science projects, try the baking soda and vinegar powered boat. Cut a simple boat shape from plastic, add a small container with vinegar at the back, and baking soda in a separate compartment. When they mix, the CO2 bubbles push the boat forward. It's a fun chemical reactions for families that combines chemistry and physics.
We do a baking soda and vinegar art project. Put baking soda on a tray, use droppers with colored vinegar (add food coloring), and watch the fizzing colorful reactions. It's one of those safe chemistry experiments at home that even toddlers can enjoy with close supervision. The color mixing teaches basic art concepts too.
The fire extinguisher idea sounds amazing for older kids! For younger ones, we do the classic balloon inflation where you put vinegar in a bottle, baking soda in a balloon, then attach the balloon to the bottle neck. When you lift the balloon, the baking soda falls in and inflates the balloon. Simple science experiments for kids that never get old.
