Mount St. Helens (with lava chamber)

Model of Mount St. Helens made from elevation data. The vertical scale is slightly exaggerated to make the terrain a bit more interesting. This model features an internal "lava chamber" which can be filled with baking soda and vinegar. If you paint it, be sure to add a clear coat to protect the paint from the "lava".

Please let me know in the comments if you have any suggestions to make the model better for table-top science experiments!
