Science and Industry Chicago

The newly-hatched chicks are always a wonder. The captured German sub is always sobering. The Museum of Science and Industry is my favorite Chicago museum, and that's a tough call, given the competition of the Art Institute, the Aquarium, Planetarium and the Field for natural history. Their latest exhibit is Harry Potter, sure to be a crowd-pleaser. And if you're in the neighborhood and want to see some great Potter-like Gothic architecture, try the University of Chicago.

But the one I come back to, time and again, is the simple magic of Foucault's pendulum, which mesmerized my kids for a precious minute or two.
