After learning about inside the Earth and the effect of the movement of the Tectonic plates on natural disasters like earthquakes and volcanic eruptions we were keen to make our own volcano and eruptions. It took 4 weeks to make the volcanoes using chicken wire and paper mache with a plastic bottle inside. For the eruption we used detergent, vinegar, bicarbonate soda , warm water and food dye. The first time we followed a recipe. The 2nd and 3rd time we could adjust the recipe!
