You think that's bad, try the Manchester Museum of Science and Industry
My 10-year-old who loves "stuff" - engines, information, science, what-have-you - won't go because it's "boring".
I have to agree. Since the refit, all of the technical stuff has gone, to be replaced by a BBC-producer's idea of what a science museum should be like. The ground floor is mostly LCD screens, and the first floor "experiments" part is usually full of broken stuff - as well as not having anything new added from before the refit. The narrative displays about Manchester Scientists (Dalton, etc) also seems to be permanently broken.
The "Power Hall" usually does not run, so no big lumbering pieces of cast iron to marvel at.
The only part that raises a smile is the reproduction Planet loco, that last time I was there would take you on a short trip around the old shunting yard lines.
