Make Your Own Fog Juice




Introduction: Make Your Own Fog Juice

Make your very own fog juice that is cheap and very effective!
All you need is a few things.

*What You'll Need:*

• Distilled Water
• Glycerin 
• Container
• Fog Machine

• Measuring Cup

Step 1: Distilling Your Water

Distilling water simply means that you are removing the minerals that build up in small pipes, such as in a fog machine.

You may have a solution to distilling your water, buying distilled water is much cheaper and easier.

Step 2: Mix Water & Glycerin

Very Thicker Smoke:
30% Glycerin | 70% Water

Medium Thick Smoke:
20% Glycerin | 80% Water

Less Thick Smoke:
15% Glycerin | 85% Water


• Make sure that your smoke is not to thick, fog can blur someone's
vision and make it hard to see where you are going.

• Measurements do not have to be exact, but should be rather close.

Step 3: Store in a Container

Store your final solution into an empty, clean container you have. Make sure to store all unused fog juice in a container before storing it. Keeping fog juice in the fog machine can clog the machine and can also cause infections to grow in the liquid, making it become no good for use. Adding a few drops of bleach to each liter can prevent infections from growing.

Minerals do not cause water to become stagnant. You are confusing bacteria & minerals. The reason it's called diSTILLed water is that it is run thru a STILL as stated by wnnorton. boiling will only concentrate the minerals as the pure water escapes as steam. ( I work in the film industry & repair fog machines as well as many other types of equipment). Most of the fog fluid used in professional setups is based on a non-toxic substance similar to anti-freeze (glycol based). DO NOT use anti-freeze,it IS TOXIC !!
Other than that great instructable !!

That steam from the boiling water is your distilled just have to capture the steam and you have distilled water. Propylene Glycol can be used as well as glycerine..both of these are the same ingredients the vaping,/e-cig industry uses to carry the flavor and "smoke" effect of electronic cigarettes. I doubt adding food coloring would change the fog color or I'm sure you would see vapers blowing out blue and pink clouds..I have been told certain flavors from my e-cig smell good and occasionally I'm told one stinks so scented fog is something to play around with. I have used lavender oil at three or four drops per quart and this works great.

Dry ice in small bundles wrapped in silk or thin cotton and placed low will help keep the home made fog near the ground and slow dissipation.. we used it this way for our band effects.

I’ve had an issue with bacteria forming in my fog machines. It says to add a small amount of bleach to the solution. Is that okay to do even though it’s being heated? Breathing bleach seems like a bad idea, but maybe if it’s a benign amount it’s not as bad?

can you use VASELINE as glycerin?

Making distilled water.

Distilled water can be created as a by-product of other devices in your home...

a) The ice that builds up in your refrigerator - though this can be quite dirty and contaminated with bits of food etc. depending on how clean you keep your fridge.

b) Water from a dehumidifier - this seems quite good. I'd recommend filtering it either through filter paper or through several thicknesses of kitchen paper to remove any dust. We use a dehumidifier to assist clothes drying and we produce several litres of distilled water every week. For long term storage, adding a few millilitres of isopropanol per litre distilled water seems to prevent any bacterial build up.

You can also use an reverse osmosis filter,from fishkeeper shops

Simply boiling water will not remove minerals. Distilling water would be accomplished by converting it to steam, then back to water, leaving the minerals and other impurities in the pan. What you have described here is a good way to sterilize water, but it will not remove minerals. The best way would be to purchase distilled water or to use a filter to remove the majority of the impurities that might cause problems.

Thank you very much for that. Boiling water can be used to remove some minerals, such as the ones that cause water to become stagnant.

Thank you for your input.

I'm sure you are wrong there. Water, on boiling vaporises and it is the vapour that is pure water. No minerals can be ever removed by just boiling, except for Ca/Mg(HCO3)2 (bicarbonates of calcium or magnesium) which form the precipitate CaCO3 which gets deposited on the vessel . However, in these times finding this "hardness" in water is very rare, and the fog might be contaminated by complexes of various 'other' salts and minerals present in non-distilled water.

Just for the info.

Great instructable and thanks for sharing :)

Im gonna make it with very thick smoke :D

Hi guys, I'm not too sure if there's a slippery finish, I just wanted to make a suggestion that if you want a cheap distilled water, I'd recommend battery's available in all gas stations and it's truly distilled.

But, saying that, I do plan on using my new fog machine in an exhibition (tiled floors), I think I have to lower the glycerine content to make sure it's not TOO slippery, if a visitor slips and breaks their back, I'm in the deep end.

hello. would adding a food coloring or some sort of scent, change the color or smell of the fog. and also, would it be possible to take this liquid put it into a container, and then like drop in something redhot and have same effect?

Thank you. U save my day ?☺

Is that vegetable glycerin or polypropelene glycol?

hi, i have been using this recipee for many years in a large town centre pub, we have wooden floors and have never found them to get slippery from the fog juice, the machine is actually a hazer and it has a remote timer which is set to give out a lot of smoke for 6 hours a night.

ps i also thought that boiling the water was the same as distilling it, i am now going to change to buying the stuff. great instructable, im of to look at your led site now. :)

If I may ask please; I bought a fog machine which uses mineral oil based fluid. I've still got a half jug of Water-based fog fluid from a previous machine. Can one use water-based fog fluid in a machine that is stated (on it's box) as one that uses Miner oil based fluid?

I don't recommend this glycerin is oil and makes floor so slippery and dirty I know i used cheap smoke juice in my disco and I had to clean up whole floor

buy some disco smoke 5liter of martin super pro juice costs 20€ in finland and you can do about 10 disco gigs with one liter

and 5l of cheapy cost 12€
some cheap juice

I use my fog machines outdoors on Halloween. Sorry, I didn't think about that, thank you for your input though.

If you are using the fog machine on Halloween, what would be best to cover the area of a garden? I'm not really caring about the plants, but how much stuff would I need?
