The seniors started building a mountain, using carbonara frames, and casting paper. After it dried they painted the mountain. Then we set the mountain down on the table with baking soda, blue food colouring and vinegar. The seniors filled the inside of the mountain with baking soda. We then mixed the vinager with blue food colouring. We took turns pouring the vinager mix into the mountain and watched as it turned into a volcano. We tried it again using water and baking soda and found it didn’t have the same effect as the vinager and baking soda.
