Nestled under the city's favorite geodesic dome (OK, it's only one), the two levels of hands-on science and natural history exhibits here bring out the kid in almost everyone. It's an ideal place to entertain the family – the gallery exploring sustainability issues is especially recommended, along with the water course of ball cannons and bridges. Expect to spend a half-day here as your sprogs run themselves ragged. Level three holds the 400-seat Omnimax Theatre, screening large-format documentary movies to those who need a sit down. If you fancy exploring without the kids, check out the adults-only After Dark events. During research, a revamp of the site was underway that will include an outdoor science park.
