A student conducted an experiment to test whether a model volcano would erupt like a real volcano. The student used malt vinegar, bicarbonate of soda, a teaspoon, and a model volcano. They poured vinegar into the base of the model and added spoonfuls of bicarbonate soda, which caused the volcano to erupt as the ingredients reacted, oozing out like lava. The experiment demonstrated that the model volcano acted like a real volcano.
