Hazer vs Fogger for lasers display

[norty303]

I use a fan pretty much identical to the one in Quazars post, but I usually put the fogger on a flightcase or 2, firing over the top of the fan, which is angled up at 45 or so degrees.
Puts the fan a little closer to the actual fog, you can use a lower speed on the fan, which in turn upsets the airflow in the room less (and hence the fog you've just put up there).

as i have only hazer, i'd go for hazer, it doesn't leave such residue as fogger can do and the fluid inside seems to be bottomless
