What’s red, yellow, and green, and shaped like a spaceship? The Brooklyn Children’s Museum. Nestled in a residential area and abutting a pretty city park, the attention-grabbing exterior suits this interactive space designed for kids—one of a few places in New York City where “little people” can run and touch and play with abandon indoors. Exhibits range from a working greenhouse to Totally Tots, where daily afternoon programming includes art experiences for kids five and under. The cornerstone is World Brooklyn, a warren of rooms dedicated to various NYC cultures—from an Italian pizza shop to a Hispanic bakery—and a replica MTA bus for fun photo ops. Feel free to bring strollers and heavy coats: the museum may be a long walk from the subway, but the coat check takes everything free of charge.
