Boston's Museum of Science is a favorite museum among locals for its varied, relevant, and highly interactive exhibits. There is truly something for everyone; the MoS does not feel like your typical stand-around-and-stare-at-stuff museum. In addition to the museum's ever-changing and always exciting visiting exhibits, there are many permanent exhibits; plan for anywhere from two to five hours to explore the museum. Plus, you have to see an Omni film. And play in the massive gift shop. Maybe just plan to come back again and see what you didn't get to see the first time; there's always more.Best and worst time to go to the Museum of ScienceBecause the museum is especially fun for kids and has so many interactive exhibits, it will be crowded when kids are out of school. If possible, go on a weekday, and avoid school vacation weeks when possible. If you must go during a vacation week, go later on in the week. Try to get there when the museum first opens at 9 a.m. or stay until after the kids are all in bed. The museum is open until 9 p.m. on Friday nights, making for a sweet albeit geeky date night.Must see/do at the Museum of ScienceSee a movie at the Mugar Omni Theater. You'll get the most out of this immersive, domed screen experience if you choose a film featuring something underwater or adrenalin-inducing.The Hayden Planetarium is also very popular as it is one of the most technologically advanced in the country, plus it offers psychadelic laser shows for a more chill evening.The Lightning! demonstration is one of the museum's oldest and still best shows. The world's largest air-insulated Van de Graaff generator will definitely spark your interest. Get to an early showing, as this popular demo fills up.Admission to the Museum of ScienceYou'll pay just over twenty bucks to get in to the museum and only save a few for seniors and children (though kids under three are free). The Omni Theater, Planetarium, 4-D Theater, and Butterfly Garden each cost about another five dollars as an add-on to your museum entry. Each of these special tickets costs about ten dollars if purchased independently. Parking and Public Transportation to the Museum of ScienceParking at the museum's garage is the most convenient option, though a little pricey. The garage does fill up on weekends and school vacation days; once again, get there early to find a spot and beat the museum crowds. You can also park a half a mile away at the Cambridgeside Galleria garage to save a few bucks (the shorter your museum stay, the more significant the savings, or take the T and save even more. Take the Green Line's E train to Science Park Station and then cross the Charles River over the bridge. Further details and directions from other T stops are available on the museum's website.Food at the Museum of ScienceThe Riverview Cafe offers some yummy choices with a splendid view of Boston over the Charles River, but you'll pay a premium. There are a variety of other options including but not limited to burritos, a salad bar, and Starbucks, but if you're on a budget, pack a lunch and save your money for the awesome stuff at the gift shop.Insider tip for visitors to the Museum of ScienceIt's certainly easy to spend hours aimlessly wandering around the museum, but you can also plan your day ahead of time to make sure you get to see the things you didn't even know you wanted to see. The museum lists daily schedules on the website including live animal demonstrations, drop-in activities and challenges, and theater showtimes.
