Spoiler: This hack didn’t work! But the 2nd build did work! Click to see working Bazooka Halloween Fog Machine

I wanted to convert my commercial fog machine that fills a room with a fine fog but can’t be used outdoors into a spooky low ground fog machine. I have seen others on YouTube do this with dry ice.  I wanted to do it with just a bucket of normal ice with maybe salt water mix to chill the 200 degree C smoke that comes out of my machine. Then the smoke should hang low to the ground in our outdoor Halloween graveyard.

This is my fog machine.

My idea was to pipe the fog into this coil in a bucket.

Add some ice.

Add some salt water so the mix will help keep the coils real cold.

Hook up the fog machine to the chiller and let the cold smoke start lofting out from under the plastic sheet taped to the garage floor.

FAIL!!! All that happen is I chilled my fog back down into a liquid and then plugged up the coil.

I tried a shorter loop.

Nope!! It too just spat out fog liquid.

In the end of the video I explain my failure and how the others on the internet using a fog machine like mine and got it to work. The hot fog is just warming their dry ice they have in a bucket and the dry ice fog is what you see coming out the other side of their rigs. You don’t need a fog machine to make that work, just a blower, box of dry ice and something to warm the dry ice. I guess it works but not the way I thought it was working. Here is a link to a hack where somebody used a similar fog machine and a box of dry ice. YouTube link: Low Fog Machine – Ground Fogger

But really if you’re going to use dry ice than just do like Kipkay did and build a Mighty Mini Fog Maker because that is all you are really doing anyway. Just heating dry ice and blowing it out a hose.

    Loved it!
    Other people’s failures teach a lot more than their successes.

    I think you have mis-diagnosed the problem here. I have built one of these using a cooler box and putting a load of frozen milk cartons inside for the smoke to weave between and it worked great. Judging from your pictures the problem is the connection to the smoke machine, when a smoke machine vaporises the fluid it needs to contact air and expand, otherwise it will immediately condense back into smoke fluid. There needs to be an air gap between the machine and the first chiller pipe. Also I think your pipe is far too thin for that to work anyway, as back pressure would stop the smoke getting pushed through.
    I hope that helps!

    http://www.youtube.com/watch?v=gncp2FPnk4k&feature=related another kipkay just using ice to drop the temp a few degrees so that the cold air stays on the ground vs hot smoke rising.

    @Edd. I know your right. I’m learning a lot from my viewers. Best thing about posting failures is others have knowledge and can help. I have set it up again with large 2 inch pipe going into an open bucket of just ice then out the bottom and it work! Then I used chipped dry ice and it work 10 times better. I spent 4 hours trying different ideas but all use large pipe no pipe at all into a bucket in different ways. I will post a video if I get time to edit all the footage.

    @pt, Yes that works I see. Like I just told Edd I tried something like that last night with a 5 gal bucket and it work. I’m going to try other ideas tonight with dry ice.

    I’ve built one of these, and I’m confident it has a lot to do with the pressure inside the chamber.

    The fog forms mostly when it goes through that tiny aperture and expands in relatively low pressure, all the ‘steam’ adheres to the glycol molecules.

    The way I did it is with dryer hose (about 5 feet outstretched) in the tub with ice (only) with the stock machine going in one end, and the hose coming out the other end. Result? Chilled ground hugging fog. If you chill it too much too fast, it will all just condense out of the air onto the pipe (you DID build a very effective condenser pipe, useful if you were to make moonshine, not useful if you want the ‘smoke’ to survive.
