Pilot experiment to determine best mix for "volcano eruptions". This was the third and best, after optimizing ratio of baking soda to vinegar (a little). This try we constricted the top of the reaction vessel to get a higher eruption (more Strombolian).
Last and best of four volcano experiments trying to see what makes lava that will stick to the sides of the volcano (so after repeated eruptions, the volcano will grow).
