Bank of England Museum
The Bank of England really wants you to understand quantitative easing. Their museum has multiple displays on the subject, plus two interactive games - one of which sees you attempting to sail a boat through stormy financial waters, applying quantitative easing in an attempt to keep inflation to the magic level of 2%.
More importantly though: they have a real gold bar in a cage, which you can both touch and pick up to see how heavy it is!Map
