Make Your Own Erupting Volcano
This is a classic experiment and it is very easy to do at home. So after you watch it – TRY IT! All you need is some kind of model volcano, and then a little vinegar and some baking soda from the supermarket. Add color and dish soap and you’re ready to go! This demonstration shows an acid base reaction. In this kind of reaction, the acid (vinegar) chemically reacts with the base (the baking soda) and the two release carbon dioxide gas which bubbles out. The liquid soap helps make the “lava” foamy.
