Smithsonian Erupting Giant Volcano Kit

Science Fun & Discovery/~Adventures in Earth Science

Developed by a Smithsonian Volcanologist -- First build your own volcano-making compound around the volcanic plastic base. Then, using a bottle and tube system and special, non-toxic erupting mixture (lava), you can cause eruptions and control the flow of lava with hand pressure. Included are three different genuine volcanic rocks, safety goggles and instructions.
