National Geographic Build Your Own The Volcano Science Kit helps create an eruption with National Geographic's exciting volcano. Your child will get to cast their own volcano (plaster and mold included), paint it (paint and brush provided), and then make it erupt (includes eruption powder). This is a great family activity and provides hours of fun for all ages. Learn about tectonic plates, earthquakes, volcano formation, and volcanic rocks. National Geographic's learning guide provides many interesting facts and is made to support a love of geology and science. This science kit includes plaster, a volcano mold, paints and a paintbrush, eruption powder, two volcanic rock specimens (geode and pumice), and our learning guide.
