We went to this primarily for the planetarium (which was great, apart from someone taking a very noisy child in with them...) but it was actually the science stuff that blew us away. Lots to play with outside which was fun to start with, but inside there was almost too much to learn! Biology, Transport (a massive train inside the museum!), Nature, Electronics... just had a really fun great day, and we dont even have kids! Thoroughly recommend for anyone who is interested in pretty much anything.
