They showed a feature about that on GMA one day a few months ago. It was totally cool! But, I'm not sure that my stomach could take that.Thanks for reminding. The Museum of Science and Industry was one of my favorite day-trips when I was growing up in Gary, Indiana. Take the kids. Be sure to take two days and go to the Adler Planetarium, the Museum of Natural History, and the Aquarium, which are clustered not too far from the science museum.
