I had a great afternoon out with my wife for only $5 per person. There was plenty to see with three floors of displays and a new area being installed on our visit, which should be open soon.
The museum had more than enough to keep you occupied for a good half a day, perhaps with a coffee in the middle, it was very informative and both me and my wife enjoyed it. I really enjoyed the engineering section with a brief introduction into steam and electrical machines in the area including displays and models of industrial processes. My wife loved the natural science and ecology displays.
