Not nearly the pizzazz of the Bellagio Fountains in Los Vegas.

And they didn't seem to work very well either! Except to produce lots of mud perhaps.

Imagine how much dust there would have been without them!

Imagine how much dust there would have been without them!

By my "sound bite" logic:

1) There is no dust;
2) The water cannons go off;
3) There is now a lot of dust;
4) The water cannons caused the dust;
5) There would not have been any dust if the water cannons didn't go off.
6) Q.E.D

Don't seemed to have worked very well...

My SWAG is that the water is meant to trap the fine dust that would remain airborne and be blown all over by any air movement. The larger dust chunks can obviously penetrate the water curtain but gravity will quickly deposit them near the demolition site.

The post demolition cloud color starts off brownish but becomes whiter as the cloud expands. A lot of that cloud is probably water vapor and not dust from the explosion.

Whooops! That's probably not what they were hoping for.

Nothing is guaranteed.
