Joe vs the Volcano!

I found this idea on and thought Joe would get a kick out of it. We have done several “experiments” with baking soda and vinegar and each time I have told Joe that the bubbles are the result of a chemical reaction between the baking soda and the vinegar producing carbon dioxide…but he just looks at me and says, “bubbles?”

Here’s the supply list:

  • container of dirt
  • a pint mason jar, no lid
  • warm water (1/2 cup)
  • dish soap (6 drops)
  • food coloring (optional, but Joe loves to squeeze those little bottles)
  • baking soda (2 TB, heaping)
  • vinegar (cup or two)
  • eager child
  • willingness to get messy

After gathering together all ingredients, put the mason jar in the dirt container and build up the dirt around it so it resembles a small volcano. The site I pulled this from used playdough and, while it looked cool, I didn’t think Joe would care either way. He is much more concerned with pouring and stirring than with shaping and molding.

Next, add about 6 drops of dish soap, the food coloring and the water. Once combined, add a couple tablespoons of baking soda and then slowly add the vinegar.

You might think that this is a lot of work for a 5 second result…well, it is. But Joe had fun stirring, adding more baking soda and vinegar and playing in the mess. He laughed and I snapped a bunch of pictures to share on here and with family. It was a gorgeous day and it was time for a break from gardening…this was the perfect experiment.
