This summer we are going to conduct many easy science experiments for kids. With summer comes the opportunity to be outside where messes are easily washed away. For our first summer learning experiment we learned how to blow up a balloon with vinegar and baking soda. This is like magic to kids and it is worth getting out the necessary materials.
Materials Required to Blow up a Ballon with Vinegar and Baking Soda
- Balloon
- Vinegar
- Baking Soda
- Funnel
- Dry empty bottle (like a water bottle)
Science Experiments for Kids – Inflating a Balloon with Baking Soda and Vinegar
Step 1: Add 2 or 3 teaspoons of baking soda to the unfilled balloon.
Step 2: Thoroughly rinse and dry the funnel.
Step 3: Pour 2 or 3 teaspoons of vinegar to the water bottle using the funnel.
Step 4: Attach the balloon to the top of the water bottle, being careful to not let any of the baking soda slip in until you are ready.
Step 5: Quickly tip the vinegar so it mixes in with the baking soda.
Step 6: Watch as your balloon blows up.
You can see our whole process in the animation above. My girls asked if we could show this science experiment to the neighbor kids, and we went and recreated this carbon dioxide experiment one more time. It was just as magical the second time as it was the first!
Why does this experiment work? The vinegar and baking soda react, forming carbon dioxide, which fills the balloon.
The Everything Kids’ Science Experiments Book is sure to add even more fun science to your family.

Made this last night with church kids they loved it wanted to do it again first reaction of one little girl was she said wow.Thanks so much for sharing this project
Awsome idea! How many times can you use the same vinegar?
woww really cool one. I love this one and would surely recommend for my students. Where is the animation?
Does it have to be done outside?
No Ive done it with Preschool students inside and they did great. Little to no mess.
I am soooooooooooooo gonna order this book.
I want some fun things to do with the grand kids over the summer.
Yes, this is a great idea! We have known about the basic science here but never did this one, perhaps outside though, I always use too much ingredients. I do not want to clean this up if the balloon explodes!

what perfect timing as the weather warms we are looking for fun and education (sshhh I won’t tell if you don’t) stuff for the kids to do–thanks for sharing-looks like fun 🙂
I think my son is JUST getting old enough to understand things like this – I can’t wait until we can do some of our own experiments.
This is so cool! I’ve blown up a balloon with water before, but I never tried this. My son will love it!
My kids love this one. Always great for the science fair too. We will have to check out this book for rainy days this summer.
