For some reason, Drachinefel's fulminations at 2:55ish to 5:00 about the National Maritime museum seem a touch relevant. I can sort of see both sides to this, as a parent, the LT musuem in London is a great place to take a small child. As a place to see and understand actual artefacts, it's not very good at all (but it is at least backed up by the depot. Which is awesome). And getting children interested is a crucial, but not the only, purpose of a museum. But to cut up an actual artefect, except for properly educational purposes, is a definite fail IMO. It's interesting how the Science Museum goes from hall of entertainment on the ground floor to way-over-my-head technical detail on the first floor.
