Volcano Experiment



Here is the ever popular volcano eruption experiment.  I remember doing this one as a kid.  My brother had a dinosaur birthday party and Dad asked us to make a small volcano out of clay.  It was tough working with the hard clay but we made a small one.  Next Dad surrounded our little volcano with a lot of dirt and a few twigs to make trees. We thought it looked just like a real volcano.

Here in this photo I attempted to re-create Dad's volcano.


  1. I found part of a box to build the volcano in. We used half a box that clothing is gift wrapped in.  The sides are flimsy so we taped them straight. 
  2. Here I made a small volcano with model magic.  That stuff is much easier to use than modeling clay/air dry clay.  Model magic is stretchy, soft and light weight.  
  3. The dirt in our yard did okay.  We (Zachary and I) poured dirt in the box and shaped it around our model magic volcano.  
  4. To make the volcano erupt I put baking soda in the bottom.  I was not sure how much to put but the more vinegar you pour in later, then the more baking soda you will need at the bottom. 
  5. Next I squirted the red food coloring in. The more the better.  
  6. Last is the vinegar. Once you mix it with the baking soda it's all coming up. 
  7. We erupted our volcano at our dinosaur play group. It was definitely the highlight of the day.
