Went there when I was little and still have memories of it. This weekend we were visiting family and decided to go out. While 4thpower Bravo went w/ my sister and her brood down to Navy pier, the boys and I went to the museum. Most of the pics didn't turn out but some really good ones.
Ju-87 Stuka. One of my favorite planes of all time.
Tesla coil. Tornado and avalanche simulators. Plasma balls. Aircraft simulators. Science displays of all kinds (we watched one on fire), the coal mine. Biology. Hatching chicks, Fiber-optics, trains, space exploration, toy manufacturing. Just tons and tons of stuff to do and see.
