    Whatever you do, DON"T add DMHO to the Fog.

    The athracene compound is similar to what Lionel used in electric smoke pellets for trains/

    Our materials guy got it straight away!

    He took the data sheet from me, looked at it for a few seconds and said "DI hydra MON oxide? Water? Then started to chuckle

    He is going to include the DHMO data sheet in the next O&M manual he compiles

    I'll bet you it doesn't get queried.

    If there's DHMO IN the fog, you're doing it wrong!

    You might want to check your heater if that happens... And get a mop.

    Diluting garden variety fog liquid 50/50 with more water (or any other ratio) will give you thinner fog and get the stuff out of the machine faster, but you'll drain the tank in no time. Spreading with a fan works better.

    Well, you will always get water in the fog, because the smoke fluid is hygroscopic (i.e. will draw water vapor out of the air).

    Even if the water isn't there in the liquid, the tiny fog droplets will very quickly absorb water from the air.

    All above arguments aside; UV reactive fog would be a hindrance in an average club environment.

    We use several kW of UV light; I would imagine there would be a white out, or an indigo out.

    If there's black-light present, sure, the entire room would probably wash out in white or a colour to some degree.

    But UV-reactive smoke/fog can also be a valuable addition to a lighting designer's toolbox. Most moving head fixtures with HID bulbs (like MSD250) have the option of a 'UV' colour on the colour wheel, which isn't very bright to the naked eye but will react to any UV-reactive substances. I can imagine it would be useful to have coloured spots in places where there's more fog or fog closer to the ground, and dimmer beams of light otherwise.

    Sure, you would probably need to think things over and keep in mind that you've got quite a bit of UV-reactive material in the air, but with some consideration, it will probably be a cool effect (whether it's done with laser or 'regular' light).
