We made a volcano out of clay. Then we added vinegar, baking soda and dish soap. We put it in the volcano and then bubbles came out of the volcano. The bubbles went down the volcano and that’s how it erupted.
Our conclusion was volcanoes erupt by baking soda, vinegar and , dish soap. They also erupt by lots of pressure. We had lots of fun doing the science project and we hope we do another cool science fair project like that one.
