We had a family day-trip to "MAGNA" over at Rotherham. It's a huge old Steelworks that has been made into a modern museum of science and industry. It is very dark inside. There is fire and very loud noise. The kids were initially terrified, then excited with an underlying feeling of unease. They did enjoy it in the end... but were very relieved to get outside and onto the adventure playground and water park. A great day out.
