16 Reasons to Explore St. Louis
Saint Louis Science Center
Dynamic exhibits, including an Omnimax theater and life-size T. rex, engage more than 1.2 million visitors a year at the Saint Louis Science Center. Visitors help power the energizer ball machine that shoots balls through a three-story obstacle course. Other exhibits allow visitors to dig for fossils, play a laser harp or create a robot. In the life science lab, kids can view their cheek cells under a microscope and learn how investigators use fingerprints to solve crimes. Don't forget to visit the Planetarium, where more than 9,000 stars are projected onto an 80-foot dome (800/456-7572; slsc.org).
