Discovery World is a science and technology center located in Milwaukee, Wisconsin. The museum focuses on innovation and technology, as well as Great Lakes education and conservation. It contains interactive exhibits, the Reiman Aquarium, and two theaters, and is home to Wisconsin's official flagship, the Denis Sullivan, a fully functional sailing vessel modeled after a 19th-century Great Lakes schooner. Many of the exhibits have to do with Milwaukee or the Great Lakes. The entire Great Lakes watershed, built to scale in the Great Lakes Future Exhibit, addresses freshwater issues, stewardship, and our relationship with freshwater resources. The museum is operated by Discovery World, Ltd.
