Big kids can purchase D.I.Y. volcano models and witness a bubbling eruption at home, but why should big kids have all the fun? All you need to make a version that will delight your toddler is a little but of playdough (as long as you don’t mind sacrificing that particular portion of playdough), baking soda, and vinegar.
Shape your playdough into a roughly conic shape resembling a volcano, and place in a tray. Hollow out a small portion in the center of your volcano for the crater.
Travis was intrigued as I worked, and couldn’t wait to help spoon baking soda into the center of the crater, already excited about what reaction might occur.
We then spooned in a small amount of red food coloring to make our volcano look like real bubbling lava, although this step isn’t necessary.
Finally, I poured on vinegar – any kind will work, and I used rice vinegar since that was all I had at home. Now enjoy the bubbling!
Travis wanted to do this again and again, which we proceeded to do until my baking soda and vinegar ran out. He even took over dumping on the vinegar himself.
Once our ingredients were gone, he played with the leftover lava “goop” in the pan for quite some time, shoveling rivulets down the sides of our volcano, and breaking the playdough volcano into small pieces. So half the fun was in the mess we created!
