Look up!

I had a meet up with my cousin Liz at the science museum.  My trains all worked beautifully, but she had problems with the buses. So I have time to wander up and down Exhibition Road (and find a book shop). It is very easy to just keep your gaze low in London, but if you remember to look up above street level, there are some wonderful details.  This is on one of the V&A buildings.
After a long lunch and lots of talk, we went to the Our Future Planet exhibition about carbon capture and the extra caught our eye - using carbon dioxide to make vodka, but no tasters though.
