Have you ever wondered how to get that spooky, ground-hugging fog for your Halloween haunt?
When using a fog machine by itself, the fog shoots out very hot, rising up into the air and then dissipates. To get that awesome low-lying fog, the fog has to be cooled as it shoots out of the fog machine. This fog chiller I made out of a kitty litter container does an excellent job at doing this!
This is actually one of the easiest fog chillers I’ve ever built, not to mention affordable, as it only cost about 20 bucks to make.
Remember, you’ll need a fog machine to use with this fog chiller (you can purchase an affordable fog machine like mine HERE) You’ll also need fog juice to put into the fog machine (you can purchase a whole gallon of fog juice HERE)
This fog chiller is an exact replica of the actual ‘Cold Fusion Fog Chiller’ which sells online for $130. This one will cost you about 20 bucks!
This is basically how it all works: The fog machine shoots hot fog into the entrance
opening which takes the fog into the upper ice chamber, then is cooled by falling down through the ice, and then exits out the bottom chamber.
There’s actually some controversy on the ‘correct’ way to use this chiller…some prefer to use it ‘backwards’ to get the same effect. The hot fog rises through the ice, is cooled down, and then exits down and out of the ‘L’ shaped PVC pipe
I have personally tried it both ways and each way worked just as well, which is why I attached both entrance and exit openings at the same height so it can be used either way.
- Hand drill
- One 2 1/2in diameter hole saw
- Hack saw (for cutting PVC pipe)
- Wire nippers (for cutting wire mesh)
- You will need one fog machine (any size) to use in conjunction with this fog chiller)
- One 35lb capacity flip lid kitty litter plastic container FREE! (if you don’t have cats, ask your cat loving friends!)
- One sheet of mesh (I used a grilling sheet for vegetables but you can find similar material in the roofing section at Home Depot or just plain chicken wire)
- Three 2in PVC couplings
- Two 2 1/8in long pieces of 2in diameter PVC pipe (in the pic it shows 3 but you only need 2)
- Four 8 1/2in pieces of 1/2in diameter PVC pipe
- One 8 1/2in piece of 2in diameter PVC pipe
- One 2in diameter right angle coupling
- One 1/2in diameter cross connector
- Four 3 1/4in pieces of 1/2in diameter PVC pipe
- Four 1/2in diameter right angle couplings
Measure and mark on the bucket where the fog will come out of the spout of your fog machine
With your drill and hole saw, drill a hole where your mark is
Do the same thing on the other side of the bucket so that you have two holes
Combine one 3 and one 4 together
Slide into one of the holes and sandwich the side of the bucket with another 3. Make sure to push together for a flush tight fit.
Now combine a 6, 7 and 4 so that it makes an ‘L’. Grab another 3…
Making sure the ‘L’ is on the inside of the bucket, combine it with the 3 which will be on the outside of the bucket. Push tight together to make it flush
This is what the inside should look like. The top of the ‘L’ should only be 1 or 2 inches below the lid
This is what the outside looks like
Combine the 5s, 10s, 9s, and 8 together.
Place into bucket. It may be easier to wait to attach two of the front 5‘s till after it’s all in the bucket. This whole contraption serves as part of the ‘ice shelf’ to hold the mesh in place.
Get your mesh ready
Cut or fold the mesh so it sits onto your pvc shelf that you just inserted. The mesh and PVC fittings serve as an ‘ice shelf’ to hold the ice that will be added to cool the fog
Time to fill it with ice!
For less of a mess and easy clean up, I use frozen water bottles for the big areas and then fill in the small areas with ice. Then I just replace the thawed bottles with new frozen ones
Now just close the lid, put your fog machine up to it, and start making some awesome low lying fog!!
