We went to Birmingham by train. The website for the Think Tank science museum suggested taking the 'Station Link' bus service, so that's what we did. It wasn't terribly easy finding the bus. There was nothing in New Street Station itself (which was no surprise really, New Street is one of the worst railway stations in the country. The planned multi-million pound replacement can't come soon enough) but there was a sign outside pointing to the bus stop.
The bus took a fairly roundabout route towards Millennium Point, taking us within sight of the building a couple of times before it finally got to the actual bus stop. We were still quite a way from the building itself, so it wasn't that handy a stop.
Things didn't get much easier when we got into the building. The huge atrium didn't make it immediately clear where the way in was. We wandered further in and only noticed the big sign when we turned round.
The museum itself was a fairly typical science museum. There was a mixture of exhibits aimed at kids (literally - many were too low for adults to use) and more serious industrial history. There was a Planetarium on the top floor. The show we attended was about the possibility of alien life and was fairly interesting.
The museum covers similar ground to the Manchester Museum of Science and Industry but with the disadvantage of charging an admission fee. Both cover the past and present of industry, with Think Tank having a floor devoted to the future. Of course both also have sections emphasising local contributions to science and industry.
The £8.50 entrance fee was a little steep. For only a few pounds more, you could take the train up to Manchester and visit a better museum with free entry.
