This place was pretty cool. First, it's located right on the lake making the views of both the lake and downtown Cleveland very nice. Upstairs on the 2nd floor it has an interactive room for kids 7 yrs and younger, our boys could've easily spent a half a day in that room only. Outside is a large, open concept room with 20+ interactive science exhibits. My kids were sweating as they ran excitedly from one exhibit to the next. On the 1st floor is all sorts of space/NASA exhibits. Extremely interesting, but for younger children the 2nd floor is where they want to be. The building is older and starting to show its age, but it was a lot of fun!
