Volcano
Activity Model
Watch a volcano erupt!
 Two great names in science - the Smithsonian Institution and Neo/SCI - have teamed to provide you with "New Ideas for Teaching Science." Safely and easily demonstrate the principles of volcanism with a realistic model which erupts internally - just like a real volcano! Actual volcanic rocks with interesting facts are included. Completely safe with no heat or flame, the Volcano Activity Model can be set up in less than twenty minutes. Eruption and continuous foaming action can be controlled by hand pressure using the unique bottle and tube delivery system. The model is accompanied by comprehensive, fully illustrated teacher and student literature including detailed reference information on volcanoes as well as step-by-step operating instructions. Size 12"D x 4"H.
