Fizzing Colors: Baking Soda and Vinegar Experiment
With just three ingredients from the kitchen, your kids will love this fizzing colors science experiment! This one’s a classic - perhaps you remember doing this as a kid? It’s the perfect project to try at home when you need to occupy your kids on a rainy day.
To make the fizzing colors: baking soda and vinegar science experiment we’re adding liquid food coloring to watch the fizzing explosions.
This activity is a great way for kids to learn about a simple chemical reaction, and also how colors can be mixed together. They’ll LOVE dropping the vinegar into the baking soda to see what happens!
If your kids are a bit older, I recommend getting started with the science experiment worksheet from the free resource library. Your child can use this worksheet to record their observations while you make the fizzing experiment.
DIRECTIONS FOR FIZZING BAKING SODA AND VINEGAR EXPERIMENT:
YOU CAN SET UP THIS EXPERIMENT IN JUST A COUPLE MINUTES!
First, pour the baking soda into a tray or baking sheet (I used a full carton of baking soda). You can smooth it out with a spatula.
Now, pour a small amount of vinegar into each glass jar and add 8-10 food coloring drops to each. You can also use an ice cube tray to hold the different vinegar colors.
Now it’s time for the experiment!
Using the medicine dropper, take some of the colored vinegar and pour it onto the baking soda.
The chemical reaction will begin immediately and you’ll be able to watch the colors bubble. So much fun!
It wasn’t long before my daughter was mixing colors back and forth. And adding bits of the baking soda back to the vinegar jars. She had loads of fun playing with this experiment. And actually, I did too.
I can’t help but think that these look like planets or something. Almost like little craters that are part of a big, colorful galaxy.
SO WHAT’S HAPPENING HERE? THE SCIENCE BEHIND THE FIZZING BAKING SODA AND VINEGAR SCIENCE EXPERIMENT:
The fizzing colors are created by a chemical reaction between a base (the baking soda) and acid (the vinegar). When the two are combined, they create the chemical reaction and produce the fizzing gas of carbon dioxide. The food coloring helps to show off the reactions and stimulate your child’s senses even more!
This project is very similar to the watermelon volcano experiment we recently created, which also used baking soda and vinegar. You should try that one as well!
While all of this is happening, ask your kids lots of questions during the process: What do they think is going on? What do they see? What do they think will happen if they add more vinegar?
By the end we had a tray full of colors!
This Fizzing Colors: Baking Soda and Vinegar Experiment is easy to set up and inexpensive to make. All you need is baking soda, food coloring, vinegar, and medicine droppers. Add the food coloring to the vinegar, then create fizzy reactions using the medicine droppers. It will keep your kids busy as they make sure all the baking soda is completely covered with color. It’s loads of fun!
