Thread: Black light fog??

Tweet

I know that they sell black light reactive fog juice on the market, but does anyone know if you can make regular fog juice glow in black light by adding a concentrated mix of highlighter ink (water and innerds of highlighter) to the juice?

I think this comes up a couple of times a year, with the argument going back and forth over whether it's safe to alter the chemical composition of fog juice, or if highlighter ink is safe to run through the heater of a fog machine...or does it produce potentially hazardous compounds once transformed into a fog...

And honestly, I don't recall if anyone's tried it successfully yet.

(edited to add: Perhaps that's the answer right there! Those that have tried haven't been able to report back to us after the experience. Hmmmm....)

Oh oh... we can all make tombstones in their honour! LOL

I agree with UJ. Everything I've read/heard about topic says DON'T DO IT! Same reason they give for not making home-brew fog juice. It's just not safe. By adding highlighter fluid, you are effectively turning off-the-shelf fog juice into home-brew.

Sorry... maybe not the answer you're looking for but none of us would want anything to happen to you, family or your friends & guests.

No, Mr Grimsley, don't apologise, I've known about the home brew stuff for a couple of years, and don't feel it's safe, I was just wondering if anyone had any thoughts or recommendations on this, as I've never read anything on the subject. I really appreciate your concern for my family and guests safety though

I used lighting effect to get my fog last year to make a RED cloud that moved down the driveway. This years I changed out the red rope lights in the flower beds and grass for green one like in the movie "THE FOG"
also if you get or rent the remake there is a lot of info and interviews with the FX team on how they made their for glow.

Well, what I'd like to have is green fog in the cemetery rising up from the ground, now most of that part of my haunt is lit by black light, and I'd hate to ruin the effect of the black light on the other props by lighting with different color lights and having that spill onto the props that are black light reactive.

can someone post the link where you can buy some?

I tried this a while back, and it did not work. I used a sprinkle of highly concentrated flourescent dye powder in fog juice. It glowed brightly under blacklight, but it didn't work when sprayed out of the machine. I think the problem was that the steam created from the fog juice was too spread out. in other words, the water particles had too much space between them to create any noticeable glow. Also, it may clog the machine. I wouldnt risk it, and just use a floodlight. just my two cents.

The fog machine works by flash boiling the fog fluid, if the ink doesn't act in the same was as the fluid it won't work.

I don't think they do sell it, but if they do, I would love to know, also. But it still might not be safe. You see, fog juice is just water and glycol, which is safe for a human to breathe for short periods of time. Adding any chemical or dye might harm you after a while
