A little bit bent...
I've read a few posts about adding glycerine to fog fluid to increase fog density. Most say don't do it as the pump/nozzle/heater may clog. Has anyone actually tried this and if so, what proportion of glycerine did you use, and were you successful in increasing the fog density? I'd prefer to buy an off-the-shelf fluid, like Froggy's Swamp Fluid, but the $35 dollar shipping charge puts it out of reach. I'm using a Chauvet F-1250 fogger.
