Good feedback. I wouldn't put "taking care" in quotes, however; my wife is a former museum worker and has graduate degrees in the field, and preservation is a key part of the role. Exhibits aren't just for the now, they're for the future. People would love to sit in the cockpit of the Bockscar bomber (little bit morbid, but true); allowing that would result in serious damage over time.

This is less important for educational spaces like the one the OP describes -- strictly speaking, science museums often aren't museums in the classical sense. Preservation is less important there, although not unimportant.
