Geology and chemistry come together in Science Academy s Volcano Lab! The fizzing reaction between citric acid and baking soda makes bubbles of carbon dioxide that looks and moves just like lava in a volcanic eruption! Based on the geology of a real twin crater island near Alaska, this hands-on science kit is explosively exciting! Contents include: safety goggles, gloves, volcano island lab station, lava bomb molds, beaker, tweezers, stirring sticks, lava foam, PH paper, citric acid, sodium bicarbonate-plus more!
