Materials You’ll Need

- Vinegar
- Baking soda
- Food coloring
- Tray or pan
- Cups
- Eyedroppers
We love using these eyedroppers because they are perfect for little hands and make it easy for kids to control the amount of liquid they use. These cups are great too, as they come with lids that have a hole, allowing kids to put the eyedropper in the cup while helping to prevent spills. You can use any tray or pan you have on hand to contain the mess and make clean-up easier.

Clean Up

This activity was surprisingly pretty clean! The reaction itself is relatively mess-free, as the baking soda and vinegar simply mix together and can be easily wiped away. The messiest part is the food coloring, which can stain surfaces if it spills. To avoid this, be sure to put something under the tray, like an old towel, newspaper, or a plastic tablecloth, to protect your surfaces. I like having my kids wear these smocks to protect their clothing during activities!
After the activity, simply rinse the tray or pan with water, and wipe down any areas that may have gotten splattered with food coloring. If any food coloring does get on hands or clothes, it usually washes off easily with soap and water. The eyedroppers and cups can also be rinsed out and reused for future experiments. Overall, the clean-up process is quick and simple, making this a great activity for both fun and minimal mess.
What Kids Can Learn
This colorful fizzing experiment is not only fun but also a great way for kids to learn:
- Colors: Mixing food coloring with vinegar helps kids learn about different colors. They can see how colors change when mixed together, enhancing their understanding of color theory.
- Reactions: Watching the baking soda and vinegar fizz teaches kids about simple chemical reactions. They learn that combining these two substances creates an exciting bubbly reaction.
- Fine Motor Skills: Using eyedroppers to add vinegar improves hand-eye coordination and fine motor skills. Squeezing the eyedropper and aiming it at the baking soda requires precision and control.
- Cause and Effect: Kids see firsthand how adding vinegar to baking soda causes the fizzing reaction. This helps them understand the concept of cause and effect, showing them that actions can lead to specific outcomes.
- Sensory Play: The fizzing bubbles and colorful reactions provide a fun sensory experience. Kids can hear the fizz, see the vibrant colors, and even feel the bubbly texture, engaging multiple senses at once.
These simple lessons make the experiment both educational and enjoyable for young children, providing a playful introduction to basic science concepts.
How to Make Fizzing Colors

- Sprinkle Baking Soda: Sprinkle baking soda evenly across the bottom of a pan or tray, making sure to cover the entire bottom. I used about half an inch of baking soda.
- Prepare Colored Vinegar: Mix a few drops of food coloring with some vinegar in your cups and stir well. The measurements don’t have to be exact—just enough to create colorful vinegar. I made four different colors for a vibrant effect.
- Start Fizzing: Have your child use the eyedroppers to squirt the colored vinegar onto the baking soda in the pan. Watch as the exciting fizzing reaction begins and enjoy the colorful display!

Variations to This Activity

To keep the excitement going and add some variety to this colorful fizzing experiment, here are a few fun variations you can try:
Glitter: Add a sprinkle of glitter to the baking soda before adding the vinegar. This will create a sparkling effect as the baking soda fizzes and reacts.
Theme-Based Fizzing: Create themed fizzing activities based on holidays or favorite characters. For example, use red and green colors for Christmas, or blue and white for a winter theme.
Fizzing Art: Place watercolor paper or thick cardstock under the baking soda and vinegar mixture. As the reaction occurs, the colors will mix and create unique artwork that can be dried and displayed.
Hidden Treasures: Hide small plastic toys or treasures in the baking soda layer. As the vinegar is added, kids can discover the hidden items, adding an element of surprise and adventure.
Sensory Play: Combine the fizzing experiment with sensory bins. After the initial reaction, let kids explore the mixture with their hands, feeling the textures and observing the changes.
