This is an interesting paradox ive experianced lately. If you want to make chilled, low lying, fog cover a large area quickly the first idea that comes to mind is to stick a fan behind it. However, this often results in the fog going out and up and every direction and becoming more of a haze instead of a spread out low fog. Now naturaly the next solution is to buy a better fog machine that pumps out a greater volume, unfortunantly that isn't really an option. Here's my hypothesis but i want to hear if u have tried this and if its worked, and what else you have tried. The haze usualy is the result from fanning the fog after it has exited tubes directing it twoard some central location. I think that perhaps if you use computer fans within fog tubes at spaced junctions then this will speed up the fog and then it will continue throught the tube thus focusing it back into a fog so the end result is less like haze. Looking forward to your responces.
