Baking Soda and Vinegar Experiment

Trying to beat the summer heat has been full of a lot of indoor fun & activities. If you missed the last post you can check it out at the end of this blog post where I will link it. Today we did a science experiment for our activity using some simple items & ingredients in the kitchen. I remember making the baking soda and vinegar volcanoes growing up. It is exciting to see the mixture explode up high so I knew I had to share that experience with my kids.

The Science

The science behind the experiment according to Science Kids. “The baking soda (sodium bicarbonate) is a base while the vinegar (acetic acid) is an acid. When they react together they form carbonic acid which is very unstable, it instantly breaks apart into water and carbon dioxide, which creates all the fizzing as it escapes the solution.

What you need:

  • A bottle or container for the experiment (we used water bottles & to keep them from falling over we set them in some old formula containers)
  • Baking Soda
  • White Vinegar
  • Food Coloring (Optional)
  • (2) Funnels

Note: we put ours in baking pans to help contain to mess as we did our experiments inside due to extreme heat but you could do this outside instead.


1) Set your container on the table or where ever you are doing the experiment. Make sure it is set up so it doesn’t fall over. Like I mentioned above we set our bottles down in some containers so they would be sturdier.

2) Next measure 1-2 Tablespoons out of baking soda and pour into the container with one of the funnels. (we used two funnels one for baking soda & the other for the vinegar).

3) This step is optional we added a couple drops of food coloring in the container on top of the baking soda to give it some color.

4) Now take the vinegar and pour it in the container until it bubbles up and out. We did not measure this out it was clear to see what was enough as I poured it, so use your best judgement.

5) Watch the reaction & repeat as many times as you want!

Get a parent to help with this experiment. This was a fun hands on project/experiment for my boys to do, they just needed supervision and guidance to do the experiment. They loved when the mixture shot up into the air!
