Once the materials are obtained, it is time to get down to work. The first step will be to line the plastic cup with clay in such a way that it simulates the conical aspect that characterizes this geological structure and place it on a newspaper. To achieve a better result, it is advisable to make a good base that supports the volcano well and thus prevent it from suffering damage at the time of the eruption. When it is ready, you have to let it dry so that it hardens.
When completely dry, the object is painted with brown paint. Other colors, such as red for the crater area or green for the base, can also be used to give the volcano a more realistic look. Then, it's time to start the most important part of the experiment: the eruption. A chemical reaction is responsible for making the homemade volcano erupt. To do this, you have to introduce a good amount of sodium bicarbonate, detergent and dye into it. Then, you have to mix them well with the help of a spoon so that they are impregnated with each other. Next comes the time to activate the volcano: by pouring a splash of vinegar inside its crater, a foam will begin to form that will rise up its chimney and the lava will begin to sprout from its walls. Why does this occur? When vinegar (acid) is mixed with baking soda (base), they react and become water, sodium acetate (salt), and carbon dioxide (gas). Carbon dioxide (CO2) is the gas responsible for the formation of bubbles that simulate this volcanic eruption.
