Watery words

I was at the synchronised swimming finals this afternoon which were really good. Those girls need to have strength, endurance, stamina as well as gymnastics, dance and swimming skills and they are all wrapped up with a big smile. Fantastic.

However. On the way out I spotted water dripping from the steel supports under the bridge only to realise, on closer inspection ( since it wasn't raining so why was the girder dripping?), that the droplets were actually forming different words. If you were walking under the bridge, by the river, all would have been clearer. How neat is that?
