One of the strange fashions of recent years is that companies who want advertise their products or a special event will take to the water. We have had giant inflatable ducks, lotto balls and even a floating lifesize house.
However, we have not had a giant birthday cake until today when the rather surreal sight made its way around the Isle of Dogs .
Londoners used to all manner of strangeness barely acknowledged it, whilst visitors were not quite sure what to make of it.
The people on the Thames Clippers and speedboats had a closer view as the cake made for E Bay made its serene way into London.
Many thanks to Alfred Gardner for the information.
