What is Volcano?
A volcano is produced over thousands of years as heat a pressure build up. That aspect of a volcano is very difficult to recreate in a home experiment. However this volcano will give you an idea of what it might look like when a volcano erupts flowing lava.
How it happens
The frothing red "lava" comes from the reaction: Baking soda (base) + vinegar (acetic acid) ==> Carbon dioxide + water + sodium acetate
