Museum of Science

The Museum of Science is colossal - easily one of the biggest in North America. It has IMAX theaters, 3D theaters, and a separate planetarium. The museum not only has an enormous permanent collection spanning several stories, but it has the largest Van de Graff generator in the world, which produces frequent electricity shows, a weather generator, many multimedia presentation areas, and at least 2 temporary exhibitions at any given time. A few exhibits remain that were designed by Charles and Ray Eames, but they are showing their age. The roster of events changes daily, and is distributed upon entry. It's worth a visit as long as you are all right with the possibility of getting a migraine.
