It’s one thing to turn on your fog machine and let it do its work. It’s quite another thing to get it to do exactly what you want and then to get creative with your machine. Here are some tips to help you make the most use of your fog machine:
• Don’t forget to duct: Use heavy-duty flexible ducting (or a PVC pipe or dryer hose) to divert fog from the exit nozzle anywhere else you want to send it. You can also poke holes in the duct so that the fog exits from several locations and rests more uniformly throughout an area.
• Does your fog hang low?: Most fog will naturally rise, but most people want their fog to stay near the ground. You can keep your fog low by building a fog chiller. Use a duct to send the fog that exits from the machine through a cooler filled with ice or, even better, dry ice. The ice will weigh down the fog so that when the fog exits the other side of the cooler it will remain near the ground.
• It can’t last forever: Keep in mind that a quart of fog fluid only lasts about two hours.
• Special Effects: Some people use compressed air to create a gunshot effect with their fog. Other people try, with limited success, to color their fog using lights.
• Things not to do: Don’t run your fog machine without juice. Don’t let the machine overheat. Don’t expect to find any colored fog fluid (even scented fluid isn’t always the best for your machine).
• Good wind/Bad wind: If you place a small fan behind the machine, the fog will hang more evenly. On the other hand, real wind will interfere with your fogmaking.
• Cleaning and Storage: Always follow the manufacturer’s instructions for your fog machine so that you don’t void your warranty. In general, however, when you’ve turned off your machine for the night, remove the fluid, and then run distilled water through the machine for a few minutes. Finally, store both the fluid and the machine in a cool, dry area.
