Pedro and the Volcano Experiment
Pedro experiments with a baking soda volcano. It didn’t quite work out as planned.

Try it yourself! Don’t worry, yours will turn out better than Pedro’s!
What you need
- Baking Soda
- Vinegar
- Dishsoap
- Water
- Cup or volcano model with container in the middle
What you’ll do
1. Scoop two tablespoons of baking soda in the cup.
2. Add three tablespoons of water.
3. Drop in two drops of dish soap.
4. Pour vinegar into the container and watch it erupt!
Baking soda is a base and vinegar is an acid. Combining the two causes a chemical reaction that bubbles and breaks up the liquid into the water while releasing carbon dioxide into the air (which makes the fizzing sound). The dish soap adds extra bubbles.

My son, Cris, now 21, demonstrated this as a Lone Cub Scout to his one-room school in México. It worked great and he got extra credit.
mine turned out better
The 1980 eruption of Mount St. Helens was far more devastating than that of Kilauea in 1983.
pedro says “ITS ALIVE ALIVE!”
How funny! I didn’t know Pedro was a science fanatic. Did Pedro make bubbles come out of the volcano?

cool
Someone to post a video on how to do this with the cup
tried it, but too much vinegar makes the volcaneo turn into a lake.
NOTE: measure your ingredients BEFORE you think to eyeball it.
My Lone Cub Scout did this as a Cub project, and got extra credit at school after demonstrating it there.
