"Home to some 35 colleges and universities, Boston is a wicked-smaht city, and you’ll feel like a genius if you take your kids to the always entertaining Boston Museum of Science. For sheer thrills, nothing beats the museum’s Van de Graaff generator: This electrifying device creates crackling bolts of indoor lightning, and the one here is the largest in the world. It’s strictly look-don’t-touch, but much of the museum is comprised of hands-on exhibits that inform and entertain—including experiments in engineering, scientific methods, model building, and math where your kids can once again prove how much brighter they are than you. The museum’s butterfly garden, fossil exhibit, and quirky Colby Trophy Room appeal to all ages, and the Mugar IMAX Theater and Charles Hayden Planetarium provide immersive entertainment about the earth and stars when you’re done exploring the three floors of exhibit halls."
