Home-made volcano!

Everyone should know how to make a home-made volcano. But, if you don't, here's how. Get a funnel, put some baking powder in it, and then some vinegar. Whooosh! (Be sure you have cleaning supplies ready, because it will make a mess) Now to the boring part. How it works! Baking soda's chemical formula is NaHCO3, and vinegar's chemical formula is CH3COOH. What happens, is the CO2, H2O and carbonic acid are left behind. The CO2 comes up in air form, the H2O comes up in water form, and the carbonic acid is left there.
