Howie Ripple Machines were used to create the effect of moonlight reflecting off the water in the London Bridge scene.

Dry Ice was used in an Antari Ice to create the effect of a mist over the river. This was not as successful as I had hoped and I have resolved to either use two Antaris or a proper dry ice system.

The rain effect was also very faint, but this might have been due to a lack of focus in the light source.

There were lots of gobos in use:

Windows: Generally OK but needed haze

Stars: too coarse, still not found anything to match the VL6

Clouds: pretty poor, except the skewed ones from the side

Breakup: very useful throughout show.
