Oregon Museum of Science and Industry (OMSI) in the 1970s had a real submarine periscope you could use, a manned space capsule you could look into, a DC-3 airplane you could go into, and a variety of whirring/buzzing physical things to interact with. In the late 90s, I escorted a school group there and it was all screens. It had gone from being a destination worth driving across the state for to being an experience less interesting than a decent web site.
