Pumpkin Volcano Experiment
A fun and engaging hands-on science experiment that combines the joy of fall with learning about chemical reactions using pumpkins.
Ingredients
For the volcano
- 1 small small pumpkin (or pumpkin-shaped craft item) Any open container can also work.
- 2 tablespoons baking soda Approximate amount used.
- 1 cup vinegar Needed for the chemical reaction.
- 1 squirt dish soap Adds to the bubbling effect.

- Add food coloring to the mixture for added visual flair.
Eruption
- Pour the baking soda mixture into the pumpkin.
- Slowly pour 1 cup of vinegar into the pumpkin's opening.
- Watch as the chemical reaction occurs, producing bubbling and overflow.
Observation
- Observe the eruption and discuss the chemical reactions with the kids.
- Encourage them to describe the colors, sounds, and textures they perceive.
Notes
This experiment is safe for young children with supervision. Materials are non-toxic and easy to clean up. Consider variations like different colors or scents using essential oils.
