We made a volcano. We have vinegar, baking soda, test tube, water and sand. We filled up the tray with sand and formed a volcano.
In the test tube, we filled it with baking soda, water and red colouring.Mix and shake.
Put the test tube on the volcano. Then we poured the vinegar. I was surprised when foam was flowing over.
