Kids love science experiments and seeing how things react. Today, we’re going to be engaging the minds of our little ones with a simple activity. This activity is a part of the Activity of the Day series.

Fizzy Fun

For this activity, we’re going to grab some common household products and turn them into a fun science experiment. We’ll throw in a little food coloring for a fun surprise on this fizzy activity!


  • baking soda
  • vinegar
  • food coloring
  • muffin tin
  • dropper or spray bottle
  • large bin

Set Up

  1. Place the muffin tin inside a large bin. This will help contain your mess.
  2. Place a couple drops of food coloring in the bottom of each muffin spot.
  3. Pour a small layer of baking soda on top of the food coloring.
  4. Drop or spray vinegar into each muffin spot and let the fizzy fun begin! (You can dilute the vinegar with water for little ones.)
  5. Repeat over and over again. You can dump the muffin tin at the end and there will be some fizzing power left still.

Babies (under 1)

For our little ones, this is a watch and see what happens activity. The adult should do all of the steps and let your baby watch. Your little one will likely be surprised when things start to fizz.

Toddlers (1-3)

With our toddlers, I recommend setting up this activity and then allowing them to use the dropper or spray bottle. They will enjoy watching things fizz and change.

Preschoolers (3-5)

With preschoolers, I recommend letting them do the dropper and spray bottle to start the fizzing. Then, talk with them about the colors. You can also have them predict which color will be in each muffin spot.

Big Kids (6+)

With big kids, you can involve them in the set up process of this activity. Have them make predictions about what will happen. You can also give them different liquids to try in place of vinegar. (Please research and make sure they are safe to combine with baking soda!)


If you want to have a little more fun with this activity, place paper under the muffin tins and let the fizzing create some fun artwork! We’ve done this activity several different times and it’s always a big hit with our toddler.

This activity is a part of our Activity of the Day series. This series was created to help parents with activities to do during school closures due to the coronavirus. Check back every weekday for new activity that you can do with kids of all ages!

Food coloring, vinegar, and baking soda make this fun experiment that kids of all ages will love!
