This Fizzy Exploding Pumpkin Volcano Science Experiment is the Perfect Fall Activity
Fill two cups up with vinegar. Or use as much as you want for exploding fun.
Add food coloring to your cups of vinegar. You can use a popsicle stick or spoon to stir the colors and disperse them completely into the vinegar.
Place small pumpkins into a baking dish with high sides or another container. This will help to catch the mess when the fizzing effect overflows and makes for easy cleanup.
