Be captivated and intrigued with hands-on explorations! The San Francisco Exploratorium is more than a science museum; it's a place that experiments with new ways for you to discover the world, connect your curiosity, and let your imagination run wild. You and a friend will be able to explore, discover, and play in the hundreds of exhibits the museum has to offer. While you're there, check out a variety of live demonstrations, involving light, life sciences, seeing, and electricity or catch a film at the theater. Demonstrations are given at multiple times daily, on a schedule that changes from day to day. Check the daily schedule when you arrive.
