Bradbury Science Museum

For such a small town, its really quite a good museum. They tell you about the Manhattan Project, and about nuclear weapons in general. As part of this, they have models of the atomic bombs dropped on Hiroshima and Nagasaki. They have a movie that explains how the government started the labs out there, and how the town was started. There are also exhibits on other branches of science, like biology and stuff. Pretty good, and in a cool looking building as well.
