Default Bellagio garden water acs - how do they work?

So I went to the Bellagio garden in vegas a couple of years back and was amazed by the streams of water that arced over one of the walkways.

What I'm talking about is the stream of water that crosses over the walkway. The arc is about 8ft high. It looks like glass.

It was so smooth that i didn't believe that it was water, until I stuck my hand into it.

So my question is, how does it work? The stream of water does not dispurse at all. No water drops come off it. It is perfectly even though the whole arc. How is that possible?

Heres the best pic I can find:

Simple, there's no oxygenation in the water when it exits the nozzle.

I watched a Modern Marvels show on this on the Discovery Channel. They use compressed air to shoot the water out of small nozzles. They also showed how they do the complex water fountain shows they do, obviously all doen by computer. One cool thing they showed was how if you focused a light beam down the path of the water it follows the arc of the water, like fiber optic cable.

I'd have thought that there was a process by which they remove the air though.

the jets are designed so that the water has absolutely no interior turbulance, that's what allows it to flow so perfectly and allow a beam of light to be carried through it (that and surface tension).

I would think so to, but after doing several projects that involve the mathematics of surface tensions and turbulance of water, I can't imagine how that's possible.

I woudl think it's something chemical or maybe they use distilled water.

IE: Water in the middle moves faster then water at the edge because of the friction between the water and whatever medium it's in. That causes it to dispurse as well as causes internal turbulance...

See my above link. Why dont you call and ask how they do it? I doubt they will give you the proprietary (SP?) run-around.

i checked it out... it's more about the company, less about the technology.

They said:
Quote:
Visually joining the two water skins are a series of steady state
Laminar Streams. Apparently motionless, and with no splash or
sound, the parabolic water arches span from one water plane to
the other resulting in a delicate and crystalline water sculpture
that reflects the ambient light and seamlessly rests within the
center of the space.
No mention of how it's done
