Part of a larger Los Angeles museum complex near the USC campus in Exposition Park, the CSC is 245,000-square-feet of interactive fun for the whole family. The first thing that catches the eye is the spellbinding 50-foot "Hypar" kinetic sculpture in the main lobby. Daredevils in the clan can take a wobbly high-wire bicycle ride--it's like pedaling E.T. home after a night of partying with Robert Downey Jr. There is a chick hatchery and Tess, a 50-foot replica of the human body and its inner workings. If your brain starts to short-circuit, get lost in a screening at the IMAX theater, which has spellbinding giant-screen films on everything from monkeying around in Africa with Jane Goodall to a 2001 space-walking odyssey with NASA's finest.
