Hey, so, does anyone remember how to make those silly volcanoes models? Like the one with the frothing lava and the bak-- [She pauses. She doesn't want to give too much away.] ...
Actually, does anyone just know how to make a good one? Scientific answers only, please.

The reaction of sodium bicarbonate with acetic acid is a simple, well-documented acid-base reaction. The partial dissociation of the weak acid into hydrogen and acetate ions results in the formation of carbonic acid, which itself decomposes into carbon dioxide and water. Carbon dioxide is responsible for the froth produced.
This is generally instructed in 6th grade chemistry.

That's how it is meant to work, in theory. A lot of children churn out methods to achieve this simple reaction and whilst most do, the most they achieve is the excess carbon dioxide froth... "Baking Soda" and "Vinegar" makes a volcano, but it doesn't really, does it? You need to model it out too? The point is to make the volcano too, right?
Personally, I never liked doing that part.

A similar effect may be observed sans volcano using an empty soda bottle.
