Fog Machines

The trick to fog/haze is understanding the air flow around where you are using it. If air is constantly circulating in, through, and past your location, it is going to take the fog with it and not leave it to 'hang'. If air flow is minimal or isolated to the location where you are using it, then the fog/haze will last longer.

Different brands of fog juice also produce different results.

Haze is much finer in 'texture' than fog. It's thinner in the air and is less noticable, but produces the brilliant beams of light you want to see. Haze also produces much better results for lasers than fog does. Haze is also easier to use for maintaining the desired atmosphere without creating a distraction, as it is a little less obvious when it starts to flow.

Sometimes you have to re-fog/haze once ever few minutes, wheras other times it requires more frequency. Different machines have different output capacities and output densities.

well from what you have said, it sounds like a haze machine is much more what im looking for than a fog machine. Do you have any recommendation of a haze machine i could buy?

First of all, Fog is better for lasers because it gives you the liquid sky effect. Haze will only make the beams look better. If have some money in your budget, I suggest the Antari X310. Its a Fazer, which combines both effects and looks great. Take a look on their website.

Hey, I work for a church doing lights and effects. To thin out the fog I use 1 - 2 fans to distribute the fog to sort of make a haze. Works VERY VERY well. Try this at your next event.
