I don't know from the posting whether the "St Paul Flat Earth Society" is a factual exhibit or a spoof or a true group of fringe crackpots. However, our Community Solar System is a fully developed education program/exhibit. It teaches one of the most misunderstood and misrepresented concepts in astronomy, the relationship between size and distance in our solar system, on a scale that is dramatic and attention getting. Basic content is presented on each of the bodies in the solar system, and a full teachers' guide is available for class visits. Several classes have visited the planets of the inner solar system (the outer planets are too far), and we get out-of-state visitors just to see the model.
