Baking Soda Experiments for Kids

There are so many science experiments that can be done using ingredients from your kitchen cabinets.  These experiments are easy, safe, and perfect for you and your children.  Grab your baking soda and try these hands on baking soda experiments with your kids. Plus, find links to more science experiments below!


The Classic Baking Soda Experiment

Grab any kind of container and pour baking soda in – the larger the container the better! Take the vinegar and slowly pour it in. The two ingredients will eventually start to react. Watch as the bubbles start pouring over the top of the container! You can put food coloring in the vinegar to create colored bubbles too!


Make Apple Seeds Jump

This is such a fun baking soda science experiment! Measure out about 2/3 teaspoon of baking soda and pour into a glass. Measure out a 1/2 cup of water and pour that into the same glass.  Take a few apple seeds and gently drop them into the mixture. Add a tablespoon of lemon juice and begin to stir the mixture.  It will start to bubble and the apple seeds will start “jumping” up and down.


Create a Volcano

For another baking soda science experiment, cut a hole in a plastic cup and glue it upside down on a piece of cardboard so the hole is facing up. Pour baking soda in the top of the hole. Add red food coloring to vinegar and then pour the vinegar into the top of the cup.  The volcano will begin to erupt! You may want to set the volcano in a larger plastic dish for easier clean up!


You can also create the same effect with dishwashing detergent and ketchup, then add water until you get your desired thickness. When you are ready for the volcano to erupt, add baking soda!


Balloon Experiment

Did you ever think you could blow up a balloon with baking soda? Try this baking soda experiment! Using a funnel, pour the vinegar into any plastic bottle – soda bottles work great! Take the balloon and place it on the end of the funnel.  Pour 2 teaspoons of baking soda into the funnel and make sure it gets into the balloon.  Take the balloon off of the funnel and put it on the top of the bottle.  Make sure the baking soda drops into the bottle. Watch as the balloon begins to fill with air!


Vinegar Ice

For this baking soda experiment, take an ice tray and fill it with vinegar. Pop it in the freezer and wait until everything is frozen.  Take ice cubes out of the tray and put them on a plate. Take baking soda and slowly pour it on top of the ice cubes! It will slowly start to fizz. If you want to speed up the process, pour vinegar on top of the baking soda.


Invisible Message

Create a secret message with this baking soda experiment! Mix equal parts water and baking soda. Use the solution as “ink” and write a message on a piece of paper using a paintbrush, sponge or toothpick.  Wait for the solution to dry. The only way to read the message is by appling heat, a light bulb will do the trick! Hold the paper up to the light bulb and it should turn the message brown.

You can also paint the paper with grape juice and the message will turn a different color.
