You could easily spend an entire day exploring this museum's aquariums and innovative exhibits that show how engineers apply science to real-life situations. The Reiman Family Aquariums follow the voyage of the S/V Denis Sullivan, a three-masted schooner that summers next to Discovery World. Don't miss the Great Lakes Future exhibit, an exact-scale model of the watershed that holds 20 percent of the world's freshwater. The technology building features interactive
exhibits such as a bed of nails, a 3-D facial scanner, and the "Rockwell Automation Dream Machine," which shows how Milwaukee landmarks use automation.
