Children learn best from exhibits involving lights and colors, which means you can either take them to a children's museum or let them rub their eyes too hard. Teach wee ones safely with today's Groupon: for $9, you get admission for two to the Children's Museum of the East End in Bridgehampton (an $18 value).

Lauded by People magazine in 2010, Children's Museum of the East End strives to promote learning through play, propelling kids throughout 4,000 square feet of classrooms and interactive exhibits designed for toddling tykes aged 0 and older. At some of the museum's 13 permanent exhibits, kids can strike a chord at the Musical Forest, crest rolling waves at a seafaring ship, paint a creative masterpiece at the drop-in art studio, and crawl up through a hollowed-out log into a tree house. Along other erudite roads, windmills spill their revolutionary secrets and potatoes metamorphose into potato chips when taunted with persistent crinkling of a cellophane bag. Outdoor mazes and gardens liberate cooped-up minds, freeing them to scamper along twisted trails and fragrant greens.

After vigorous bouts of interactive learning, parents and progeny can seek snacks and drinks at the MoonSoup gift store. The museum occasionally refreshes its lineup with new temporary exhibits, and it regularly schedules classes that, for an additional fee, delve into hands-on lesson plans covering music, art, interpretive temper tantrums, and cooking.
