Dropped in on a whim, did not know this was there. This museum is apparently supported by 3M, but you are asked to pay $5 to enter. The museum is very small (3, bedroom-sized spaces), and is merely a history of the company (no artifacts or education to speak of). Further, there is nothing here from the past decade (looks like time stopped in the early 2000's).
It is an advertisement of 3M, and I felt cheated having to pay to visit.
If this was free, supported by 3M, it would be worth the stop. This is not the case, and based on what I saw, I would suggest passing it by, even if you are interested in science and industry. I'm proud 3M is a company in my city, but this 'museum' is a joke.
