A volcano erupting in the class

As some of my students studied weather disasters for example: tornados, hurricanes, drought, flood, earthquakes, volcanoes, we did an experiment in class. They learned about the different parts of them ( crater, cone, lava, magma, ash, crust and smoke).They also studied about the Vesuvius in Italy. The experiment consisted of building a clay volcano and watching it erupt with red food colouring some vinegar and bicarbonate of soda. Students were flabbergasted and so was I.
