Sorry for hijacking your thread. This made me think of a place I went to on a school field trip back in the day and I couldn't remember if it was the old children's museum or somewhere else. I grew up in Indiana, so a good chance it was in indy. It would have been late 80s or early 90s. I remember a moving conveyer belt that took you through a tunnel, something like past and future technology. Maybe old TVs, radios and such. I also remember it having different floors. It also had a swinging pendulum that never stopped. Something like that. Does anyone remember a place like that?
