I recommend purchasing the audio guide. It made all the difference. If I would have gone without it, I would have been very disappointed in paying so much for the very short descriptions written next to each device. The audio guide on the other hand gives you a detailed description and historical stories. The audio guide will be on your phone so make sure to have charge on your phone. The employee will give you a website and password to access the audio. The Microart was interesting, but I wouldn't pay extra to see it. We had a good time and enjoyed this museum. Something different. I would recommend you check it out.
