Erupting Volcano

We put bread soda into a small bottle. (We also added red food colouring for effect, and wash up liquid for bubbles). Nothing happened yet.



Next Thomas poured in vinegar and the volcano exploded, sending out bubbly red lava. This is because bread soda and vinegar have a chemical reaction together, giving off lots of bubbles (of carbon dioxide).
