the volcano erupted for 22 min!

the reason the volcano erupts is because

The baking soda and vinegar volcano erupts because of an acid-base reaction. The baking soda is a base called sodium bicarbonate. The vinegar is an acid called acetic acid. When you combine the two, one of the results is a gas called carbon dioxide, which makes all the fizzing and bubbling tha looks like cool lava.
