What you will need:

  • a box or cooler
  • 1 roll of 1/8in copper tubing
  • 1 1.5in connector with threaded end
  • 1 rubber connector with hose clamps
  • 1 4in dryer duct connector (for each outlet)
  • 4in dryer ducting(the white flexible kind)
  • silicon sealant
  • dry ice
  • fog machine
This is a very basic, yet extremely effective way to cool down your fog so it remains low flying. The first thing you need to do is build a box or use a cooler. Next you will need to cut an approx. 4in hole in 1 end and a 1.5in hole in the other. Now install your dryer duct fitting into the 4in hole and the 1.5in threaded fitting into the other. You then will need to bend the copper tubing into a radiator shape (I built a jig, that would allow easy and non kinked bends, but it really doesn't matter). I added 3 sets of these radiator shaped tubes into each of my coolers. The more radiators you have, the better cooler you have. The copper tubes act as a transport for the cold to travel upwards, to where the hot air will be flowing. Since cold air normally stays low, while the hot stays high, most coolers are rendered useless. Now that you have your radiators bent and inside the box, glue the edges down and allow them to dry overnight.

Once the glue is dry add the rubber connector to the 1.5in fitting and the other end of the rubber fitting onto the nozzle of your fog machine. Connect your dryer ducting to the exhaust port and run it to your desired area. Finally, add your dry ice*, seal the top and your ready for business.


Here are a few pictures of how the fog looks.



*The copper tubing makes a shrilling sound when it comes in contact with the dry ice, so be prepared.
