W.A.L.T Description of how volcano.
Today we exploded the volcanos we have been making for the last 2 weeks.
We made them out of paper mache but it didn't work very well. I think we needed more baking soda in it.
We put water, baking soda, and vinegar witch released a gas called carbon dioxide.
This was super fun making it and exploding it.
