Arthur's recovered sufficiently to engage us in water pistol battle.
And to drive around the London Transport Museum.
Then we went to see an exhibition about badges at the British Museum. The smallest exhibition room you've ever seen, basically a cupboard, but you get what the Design Museum would stretch over two floors. Worth going to see. Especially as it's free. Reminded me of the splendid Project Button. Then we had a random wander around looking for bones. Very succesful.
