Cut the top off your pumpkin.

Have the kids scoop out the seeds and pulp. It doesn’t have to be perfect since it’s only the container for the experiment.

Add ½ cup of baking soda inside the pumpkin.

Add food coloring if you’d like. You can put it under the baking soda for a surprise or mix it with the vinegar.

Mix dish soap with vinegar in a separate cup.

Slowly pour the vinegar mixture into the pumpkin, watching it bubble over. Stir or add more vinegar if some of the baking soda is dry.

Repeat as much as you like. The more ingredients you add, the more foamy fun you’ll see. Enjoy!
