Bristol’s whiz-bang science museum is hands-on and highly interactive, and will thrill the kids. In zones devoted to space, technology, the science of food and the human brain, they can spin on a human gyroscope, chat with a robot chef, walk through a tornado, and strum a stringless harp, among other things. In winter, the museum hosts an ice-skating rink. And in 2014 it set a record for creating the longest string of popcorn (a whopping 320 meters long!).
