We learned about volcanos in geography and decided to do an experiment in science. We mixed vinegar (acid) and baking powder (base) and they reacted.
We called it an explosion!  It was red because we added food colouring.
We were surprised that it errupted for so long.
We predicted it would be hot like lava but luckily it was cold.
We all touched it!  It felt wet and foam like.
