- Large tray
Set up in a snap
It’s just about taking your materials and setting them up so they’re accessible for everyone! We like doing these kinds of activities on low tables so that the kids can see inside of the pumpkin as it’s fizzing.
- Place the pumpkin in the center of a large tray.
- Set bowls of baking soda around the table. Add in spoons.
- If using coloring, add it to the vinegar and place those bowls around the table, too. Add in spoons or eyedroppers.
- Let the littles mix and match!
Note: Sometimes, we add a few cups of baking soda into the pumpkin to start to give it some height. Our students love seeing it ooze out of the side of the pumpkin, and a bit of vinegar to begin helps to achieve this.

What else reacts with baking soda besides vinegar?
Lemon juice! We LOVE making lemon volcanoes, and you could easily add fresh lemons cut in half instead of or in addition to the vinegar.
If you are sensitive to the smell of vinegar, do this project outside. Personally, the scent of vinegar makes me 🤢, but projects like this don’t bother me at all when we are outside.
Ask juicy questions like this to deepen the learning and fun!
When the kids are doing their thing exploring and experimenting, adults can engage them in open-ended questions to facilitate discussion and deepen the play.
Before the activity:
- How does the pumpkin smell?
- What is inside the pumpkin? How does it feel?
- Why do pumpkins have seeds?
- What do you think will happen when the baking soda and vinegar get mixed in the pumpkin?
During the activity:
- What sounds do you hear?
- How does it smell?
- What happens if you use a LOT of vinegar on a little bit of baking soda?
- Will this make the pumpkin explode?
