Housed in a converted 18th-century factory, this modern science museum keeps children busy with interactive exhibitions, games and scientific curiosities. The Planetarium guides kids on a galactic voyage of discovery, while the Science Gym tackles the mysteries of evolution. Suitable for threes and over, it's a brilliant hands-on day out. There's also a popular programme of workshops, which need to be booked in advance. Families can easily spend the best part of a day here, lunching at one of the on-site restaurants.
