Thread: Neat lil' fog trick

Tweet

Hey all, do you want to know a cheap way to make fog cooler without making an expensive chiller with the works? I have a solution. Here's what you need:

a fog machine

a long piece of PVC pipe (the middle thick enough to fit over the fogger's spout)

a grate (or a circular piece of wood with big holes taken out of it)

some tape

First, you'll need toplace the PVC pipe on the spout of the fogger. Then, tape the grate on the other end of the pipe. This trip the fog takes will make the fog cooler and make it lay on the ground a little more than if you just use the fogger without the pipe. Another suggestion is placing the end of the pipe in an area where the fog will be needed, like a graveyard scene, but hide it cleverly behind a tombstone or some shrubery.

I have been using pipes, only I fill em with ice, works great, and can have my fog machine hiding, only prob is disguising the pipes sometimes, and when you do disguise em, you have to pull em up to refill before the next nites show.
I have a large pumpkin with a hole in the back for the pipe to run in, and then I have a witches cauldren I do the same with.
I use straw to cover em.

$20 Fog Chiller

I too went the PVC pipe with ice route two seasons back. Worked like a CHARM!!!

I built that one too Freak last year, however the wind caused it to not work as well as when I tested it originally....hoping for better this year and will be adding a second fogger with chiller for sure, trying a cooler style.

If you went mrh's route of just the heatsink method with the pipe and no ice, do you think using aluminum stovepipe or downspout would cool it more? Aluminum is great for sinking heat; does a good job keeping my computer from frying heheh

I can see benefits of going this simple route if you don't need the fog bone-chilled... maybe it would rise a bit more, giving a more ambient body-level fog instead of just pools on the ground. Hmm... need to test... gotta buy some froggys

Using dryer vent tubing ( either the plastic or the shiney version ) works really great , is flexible so you can bend and angle it any way you choose and , if you place it properly ( leave at least 2 inches from the tip/nozzle of the fogger to the beginning of the tubing ) , you will get EXPANSION , which is why , with NO cooler , or piping , the fog blows away in the air before giving a good show .
When the fog is allowed room to expand ( which is what happens naturally when it comes out of the fogger ) it will hang lower and also allow the fog to get thicker than if you just let it come straight from the fog machine into the air .
Try it ... it only costs about $4.00 for a flexible dryer vent hose tube :
( see pic below )
This picture is of the shiney metal one , which is what I use and holds up really well . If you get the vinyl version , and you get it too close to the fogger nozzle , it will melt the vinyl, so you have to make sure , you leave enough room for two reasons - 1) to allow the fog to expand 2) to prevent your vinyl tube from melting . ( unless you simply use the semi rigid metal one )
This comes in differnt lengths and you CAN join them , but , I would not suggest going over 10 foot in length anyway ... unless your fogger has a HIGH pressure output .

I did something along those lines but I added frozen bottles of (Rock)salt water in different turns in the drier hose.

was just thinking about a project i came up with for an instant beer chiller in my tailgating days that may work for this application...

take an old cooler...ice chest whatever you want to call it...and pop a hole in each side. Take some tubing (we used thin wall copper tubing for the beer) and coil it inside the ice chest (you could probably go with the coil of dryer vent tubing for the most effective heat transfer).

Run your inlet (keg, or in this case fog) and the outlet tubes to the cooler and viola...instantly cold beer...errr...fog. Because of the coiled design this will take up a minimum of space and can be disguised as a tombstone, or other prop quite easilly. This will also keep the ice colder longer as it is better insulated and it's only heat introduction will come from the fog, instead of the environment as well.

I will draw up plans for this and attempt to post if anyone is interested...but I think it's pretty self explainitory.

hope this helps. If anyone tries this (i may just have to buy a fog machine and try it out myself) please let me know how well it works.

I tried this using a refrigeration coil in an ice chest. The simple fact of the matter is that for the sake of ease and convenience it is just easier and more effective to have a chicken wire tube run through the ice. The fog passes so fast trough the coil that it doesn't really have any effect.

bummer...though it would work...well, at least I'll have cold beer and we all know that aside from free, COLD beer is the best kind out there!!
