As a child who lived in London, I went to the Science Museum at least
once a year. I loved pushing the buttons and turning the wheels to see
what the exhibits did. About 10 years ago I went back for the first time
in 40 or 50 years, and was very disappointed. Most of the displays were
static - there were few buttons, wheels, or levers. I couldn't see how
these displays were meant to stimulate a child's imagination.

Friend of a friend worked in the Science Museum. In the farming
section, they used to have a demonstration of a milking machine.
One of the cups was mounted so that you could insert a finger and
feel the action. Small boys were a bit more imaginative, and they
ended up having to relocate the cup somewhat further from the
ground.
