Set up the perfect pumpkin volcano science activity! Fall is my favorite season! Anything pumpkin is always fun, whether you eat it, carve it or turn it into hands-on science! Our pumpkin volcano science activity is hands down the most requested pumpkin activity of the season. In fact, we decided to make an erupting apple volcano too! make sure to check out this great collection of classic pumpkin science ideas with a twist for more creative ways to use your pumpkins.
PUMPKIN VOLCANO SCIENCE ACTIVITY FOR KIDS
Our Pumpkin Volcano Science Activity is Easy Science!
Simple science activities you can make with quick, accessible, and affordable ingredients is my favorite kind of science! Any sort of baking soda science eruptions are sure to please any kid and adult too. Our year of preschool science ideas has many fun ways to enjoy simple science experiments. like this pumpkin volcano science activity at home
WE ALSO HAVE SOME GREAT PUMPKIN BOOKS PAIRED WITH PUMPKIN STEM ACTIVITIES!
SUPPLIES FOR MAKING A PUMPKIN VOLCANO

One small pumpkin, baking soda, vinegar, food coloring {optional}, dish soap, and water.
First , get your pumpkin! I bought this baking pumpkin for $2 at at the grocery store when I was shopping. All the way home Liam talked about making a volcano because he remembered the volcano we made in our dinosaur sensory bin. The bigger the pumpkin the more baking soda and vinegar you will need and the bigger the mess you will make!
Second, you will need to hollow it out! This is a fun activity on its own and great for pumpkin sensory play. Save the insides for some additional sensory play if your child likes messy and squishy play. I planned to make a sensory bag with the gooey stuff so he could examine it more later! I loosened the insides and gave him different kinds of spoons to work on scooping out the seeds and stuff. You could also carve a face!

Third, find a container to put inside the pumpkin or use the pumpkin itself. We couldn’t decide which to try since we had never tried this before, so we ended up trying it three different ways. We used a cup, a small soda bottle and the pumpkin itself to test out what kind of eruption would happen with each.
WHAT’S THE SCIENCE?
We talked a bit about why the eruption happens. The baking soda is a base and the vinegar is an acid. When they combine a chemical reaction takes place and a gas is produced. The gas is carbon dioxide which fizzes and bubbles. This is easier done by showing him the reaction, so we added the vinegar! We also explained that another type of reaction is the surprise he felt when he saw the fizzing foam come out!
Here’s the mixture I made to fill the cup, bottle and pumpkin:
- 1. warm water mixed with food coloring filled to about 3/4 full
- 2. 4-5 drops of dish soap
- When you are ready to make the eruption
- 3. A few tablespoons of baking soda: then get ready to add….
- 4. 1/4 cup of vinegar and watch with delight!
Here are the variations with the soda bottle and just the pumpkin!
With this variation of the science activity, the eruption got a little more height so it looked a little different from the others. When we were done with the bottle, we took it out and dumped it into the pumpkin which created a huge eruption and led us to just try it in the pumpkin itself!
ALSO TRY MAKING: Pumpkin Oobleck!
As you can see from his expressions he had a great time with this pumpkin volcano science activity. He wanted to be the one to make the reaction happen after he saw us do it the first time, so we let him pour the vinegar by himself! We had lots of eruptions from this little pumpkin and lots of mess!

This was one of my favorite pictures of our pumpkin volcano science activity! The pumpkin was completely surrounded with fizzing, foaming, bubbling ooze! Fall is an awesome time to experiment and explore with nature with all kinds of autumn activities for kids including a pumpkin-cano.
THE PERFECT FALL ACTIVITY WITH A PUMPKIN VOLCANO!
This is awesome!! We love vinegar/baking soda science!!
Hi there! I found you on Mom’s Library link up. This is way too cool! My kiddo is 7 and will just love this. Never would have thought of it, thank you. Pinned! 🙂
Thank you! So glad you found us. I imagine it will be a hit for years to come!
I LOVE IT! I know both my girls would really love this and want me to do it over and over again! Thanks so much for sharing on We Made That Wednesday!
Oh yes! I am sure we will be doing it again. He was eyeing the huge pumpkin outside. Could you imagine what that would do?!
We have a few pumpkins begging to be cut open. This looks like such a fun way to put them to use! Thanks for sharing at Discover & Explore. I’m featuring this post today.
Talk about a great way to kids involved! (especially those that may scrunch their nose at slimy seeds–they won’t be able to turn away from this!) Another great idea from you! Thanks for sharing at Magic Moments Monday.

Ohhh never seen this one before! Bet my boys would LOVE to try it with a pumpkin 🙂 x
Appreciation to my father who informed me on the topic of
this blog, this website is truly awesome.
Hello,
Just wondering why do you add the dish soap?? My mom is a science teacher and I have never seen her add dish soap to her volcanoes for class. Thanks for posting this fun idea. My neice will love it!!
Add it after baking soda and before vinegar. Or you can gently mix it into the vinegar. You don’t need it as the reaction happens with the other two ingredients. The soap makes it really froth!
