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.
