Projection screen nozzle/sprinkler

Hello folks, I am new here, but I have a serious problem and don't know what kind of sprinkler or nozzle to use to create a mist/water or fog screen to project images and video. I found several videos in youtube to what I need to create and I leave you all the links to see if you can help me create this handmade mist screen. Thanks!

Water fog is best created by aerosol methods, using both water and pressurized air.

Great!, do you know any model or nozzle that could do that job?

sorry, but aerosols are out of my area of expertise ~ I researched various water-only fogging nozzles for a special industrial application, and from the literature, I could see that aerosols could produce a finer mist by far.

Also, read this page, and see that this idea has additional complexities, with the screen being a "laminar flow" of mist, created by ultrasonics.

Thanks! I read the webpage. It seems that that mechanisms creates a screen that goes from up to down when the fog lays down. What I need to produce is a system that goes from down to up. In the first video I posted, the person who handmade created the screen wrote down the materials, these are:

3/4 pipe and proper fittings to cap one end and connect the other to a valve
pvc blue hot glue
valve (sprinkler preferred)
pvc pipe cutters
a transformer that puts out 12v to turn the valve off and on

I am a newbie when talking technical terms such as valve and the electronic system, could you please explain me what does he means by "valve (sprinkler preferred) and a transformer that puts out 12v to turn the valve off and on" ? Perhaps an image? Thanks!

Champion makes a brass spray nozzle that throws water straight up in a fan, to water strip areas. Get one or more of those for a cheapo version of a water screen.
