Your Own Fog Machine?
We’ve all been to a party or event and witnessed a fog machine in action. The way that it seamlessly fills the room with a hazy smoke-like vapor and transforms everything it touches looks like magic! It proves that a fogger has the power to quickly change any area into something special.
While it would be nice to be able to have your own fog machine to use for birthdays, parties, and Halloween decor, sometimes the cost just isn’t feasible. However, that doesn’t mean you have to go without the cool effect. In fact, you can learn how to make a fog machine with only household items!
That’s right, in this article we’re showing you how to make your very own DIY fog machine. Just by using a few things that you probably have around the house, and a little bit of patience; you can get the cool or spooky vibe that your party needs.
With a homemade fog machine, there’s no need to spend a lot on decorations or party planning, because you’ll have all the atmosphere you could ever hope for.
Should You Make Your Own Fog Machine?
Although there are plenty of great fog machines out there with all types of capabilities, it’s not always feasible to purchase one. You might have a perfectly good machine already, but be in need of a second for a larger event; it could be broken, you might be low on funds, or simply want to experiment with making your own.
The best choice is always to purchase a machine, and because they’re now easier to make, it means they’re usually more affordable as well. For the purpose of this experiment though, we’ll assume that it’s not within your limits and you want to take some time to create your own DIY fog machine.
Or maybe it’s the case that you simply enjoy making your own things from scratch! This can be a fun DIY project, and you’ll get a real sense of satisfaction from making your own smoke machine at home. It’ll be much more satisfying pumping out that smoke if you know you’ve had a hand in every stage of the project.
Once you have this up and running, there are plenty of opportunities for how you can use it. A fog machine is especially handy for a Halloween party to give a spooky vibe, but anywhere you can think of that needs a boost in the atmosphere, your new DIY fog machine will be able to come to the rescue.
How to Create the Fog Juice
All fog machines, whether store-bought or homemade, need fog fluid to get them going. In fact, fog fluid is much more important than many give it credit for. It makes all the difference in the quality of your smoke, and is necessary to create that thick, noticeable fog effect that you are used to seeing.
Thankfully, this is just as easy to make for yourself at home. Follow these steps to create your own fog juice that you can use for any of your machines.
- Grab an empty and clean quarter gallon plastic bottle and ensure there’s nothing inside
- Depending on the level of thickness you want from your fog, there are different measurements for the distilled water and glycerin mixture
- A thinner fog should have about 15 percent glycerin and 85 percent water, whereas something thicker would be around 30 percent glycerin and 70 percent water
- Test your solution first and see if it makes fog; otherwise, you may need to go back and readjust the measurements until you get it right
Types of DIY Fog Effects
As mentioned, the proportion of glycerin in your fog machine solution will determine the density of the fog effect you are creating. Here’s a quick outline of the types of fog, and what they are best for:
If you use a lighter proportion of glycerin (roughly 15%) in your fog machine fluid, then you’ll end up with a fog that is much thinner, and is known as “haze”. Haze is considered the thinnest type of fog.
It is meant to be almost completely transparent but does an excellent job at amplifying lighting effects. The lights cut through the haze, and make them much more noticeable to spectators, adding an extra element to your party or show.
Medium-density fog is a great middle ground. It’s transparent enough to not block people’s vision too much, but also thick enough to create a noticeable fog effect. The best of both worlds really!
It’s a great fog if you’re looking to amplify any party, add some mystique to your decorations, or create theatrical fog for a performance. It will be around 22-25% glycerin in the fog juice mixture.
High-density fog is the most opaque fog. It almost completely blocks vision, and is the most noticeable fog effect achievable. If you really want your fog to stand out, this is what you want. It’s achievable with about 30% glycerin in your mixture.
Because it is so opaque, it is not ideal for parties and events, because it might create a safety hazard by obstructing people’s vision. Therefore, it’s best for theatrical and decorative purposes, enhancing your display with a thick layer of fog.
How to Make Your Own Fog Machine
With your fog juice at the ready, you can now start creating the fog machine. You should be able to find most of these items around the house, so gather them up before you begin the project.
- One large candle with two or more wicks
- The top of a two-liter plastic bottle (a plastic soda bottle works best)
- Small aluminum pie plate
- Homemade fog juice
- An old can of soup, empty and clean
- Sticky tape and scissors
Step 1: Ready the Materials
Gather all of your materials together, including the homemade fog juice, and start by cutting the top off the 2-liter plastic soda bottle and keeping it for the machine. Dispose of the bottom half.
Step 2: Tape It Together
With the cut end of the bottle, tape it onto the pie plate so that you’ve created a cone shape when the two of them are together. This will be your homemade fog machine.
Step 3: Positioning
Get the empty soup can and remove the lid. Place the candle into the can and light all of the wicks on the candle, letting them burn a little while to ensure they won’t go out. If you’ve managed to find a large store-bought candle that doesn’t require a can, this is fine as well.
Step 4: Poke Some Holes
Next, place the fog machine over the top of the can and allow the heat from the candles to get to it. Poke some holes in the bottom of the soup can to give it ventilation.
Step 5: Complete the Fog Machine
Once everything is all combined, and the candle is lit, you can now add your fog juice. Start with just three teaspoons and add it to your homemade fog machine. When it starts to get low, add a few more. Just this small amount should be enough to make fog for at least half an hour.
How to Make a DIY Fog Machine with Dry Ice
Another popular option for a homemade fog machine is by using dry ice. If you’re familiar with dry ice, you know that it already makes a “fog effect”. So, it’s really just about harnessing the dry ice, and using it yourself.
The primary difference here is that, because dry ice is very cold, the “fog” it creates actually sinks to the ground. Therefore, we will be taking methods to heat it up, so that it creates fog similar to a traditional fog machine.
To make a DIY dry ice fog machine, you will need the following supplies:
- Dry ice
- 5-gallon bucket
- Hot water
Step 1: Fill the Bucket
Start by filling the bucket halfway with hot water. Do not fill the bucket all the way to the top or it will overflow as soon as you add the dry ice to it.
Step 2: Add the Dry Ice
Using gloves or tongs, you can begin placing the dry ice into the container with the hot water. You want to do this very carefully while avoiding any kind of splashing.
Step 3: Place the Fan
Now you will place the fan so that it will blow the smoke that is created with the hot water and dry ice combination. Make sure to set up the fan, so it blows the smoke in the desired direction.
Step 4: Replenish
As the water cools, you will need to add more hot water to the bucket. You will also need to add more dry ice. Putting a bigger chunk of dry ice in the water can result in a longer-lasting fog effect. You can also get a hot plate to keep the water warmer for longer especially since dry ice will result in rapid cooling.
Always make sure you are in a very well ventilated area if you choose to make your own fog machine using dry ice. You also need to practice extreme caution when handling the dry ice because if it touches your skin, it can cause frostbite.
Fog Machine Safety Tips
Whether you make your own DIY fog machine or purchase one online or in the store, you should still follow the same safety tips and precautions. Always make sure that the fog machine is being used in an appropriate manner. You want to have a good amount of visibility and ventilation available as well as space for people to walk without bumping into the machine.
If you purchase a fog machine from a store, it should come with its own set of safety instructions or handling requirements. Be sure to follow these above all else. Not only will they tell you the best ways to handle the machine, but you also might void the warranty if you handle your fog machine improperly.
Always set up the fogging machine away from flammable items. The area it is in should also be easily accessible for you to make sure it is operating as it should.
Finally, make sure to use or make the appropriate fog liquid in your machine. Don’t mix and match different liquid types either.
An Instant Atmosphere Booster
While it might not look as professional as a real fog machine, nor will it make as much spooky vapor, this is still a great DIY project that you can try at home. Halloween is a great time to try this out and get your kids involved, so long as you are supervising them when it comes time to light the candles.
The addition of a fog machine to any event will boost the atmosphere instantly, and there’s no need to spend a lot of money just to enjoy it for yourself.
With this easy homemade fog machine, you’ll learn something new about science and find a great new way to decorate, and best of all, there’s no need to purchase any of the materials because you’ll already have them on hand.

DIY Fog Machine FAQ
How Does a Fog Machine Work?
Essentially, a fog machine works by heating fog juice to the point where it becomes vapor. Once this vapor is exposed to the colder air outside the machine, it takes on the “fog” appearance you are familiar with. Of course, this is a simplified explanation of what actually happens. For a more detailed guide, check out our fog machine basics.
Can you use water in a fog machine?
Distilled water should be used in a fog machine. You never want to use tap water or mineral water because both of these waters contain impurities that will end up clogging the fog machine.
If you’re using a dry ice fog machine then you might want to make lots of distilled water and store it in a 2-liter soda bottle because dry ice will require constant top-ups to keep a good water level.
How much fog liquid do I need to make?
The amount of fog liquid you need depends on the size of the fog machine you are making. The bigger it is, the more juice it will go through. The duration of fog production also affects the amount of fog liquid you need. One batch of fog liquid will only produce fog for so long. For continuous fog all day long or for extended periods of time, you’ll need several batches.
Can you use a fog machine outside?
When you have the fog machine outside, you will find that the fog disperses much more rapidly than it would if the machine were indoors. It is recommended that you test your machine first to see how it will function in the location you need it in. However, many store-bought fog machines are not waterproof, so you will need to be careful to bring them back inside if there is a chance of precipitation (or keep them covered).
Can you make a fog machine with dry ice?
Yes. You simply fill a container halfway with hot water and then add a few pieces of dry ice very carefully to the water. When doing this, it is important that you wear gloves. As the water begins to cool from the ice, you will want to add more hot water so you can continue to maintain the fog effect. One pound of ice will typically create two to three minutes of fog. See above for more detailed instructions as well as a warning about the dangers involved with dry ice.
What Makes Great Looking Fog?
You can create all sorts of special effects by adjusting the density and temperature of your fog production. The type of fog you need usually depends on the type of special effects you want to create. Here’s a quick look at the different uses people usually have for different types of fog.
The Best Fog For Stage performances
For stage performances, you might want to combine two different types of fog for the ultimate effect.
Haze fog is a light and thin fog layer that fills the entire room without making it too hard to see what’s going on on stage. The main benefit of this type of fog is that it helps reflect light. When you shine a spotlight through a room full of haze, it will create a solid beam of light that’s ideal for highlighting certain elements like your stage performer.
Different colored light bulbs can also be used to create unique beams of light for a spectacular display of color and light.
You might also want to create a low-floating fog that oozes over the stage down towards your audience. This type of fog is usually achieved with a chilled fog solution like dry ice along with a chilled fog machine.
The Best Fog For Spooky vibes
For spooky or eerie vibes like Halloween, haunted houses, or theme parties, you will want to opt for loads of low-floating fog. The low floating fog will cover the ground and loam about gravestones to create a scary look. The white fog is usually preferable for this type of setup because it offers a ghostly effect.
The best way to achieve a spooky vibe is by creating a dark room that is filled with low-floating fog. You can position your lights low to the floor to enhance the look of the fog.
The Best Fog For Cloudy vibes
For some events, you might prefer a cloudy and heavenly vibe. These types of vibes are perfect for certain parties, light, daytime events, or cloud-like or heaven-themed photoshoots or videography.
Low-floating for that stays close to the ground to form thick clouds all over the room surface is ideal. With this type of setup, you will want to hide away your fog machine and continuously produce thick fog.
Two fog DIY dry ice machines might be a great solution because if the water of one turns cold, you can start prepping the next batch in an additional machine for continuous cloud formations.
The Best Fog For Fiery scenes
To create a backdrop or room setup that looks like it’s on fire, you will want to create thick chunks of high-floating fog. The fog produced with DIY fog juice is perfect for creating this type of setup because this type of fog isn’t as likely to collect at ground level as dry ice fog. Instead, it floats about in the air to create a smoky look.
You can combine this type of fog with warm light or red bulbed floodlights to create a toasty scene.
The Best Fog For Smoky backdrops
For videography and photography, you might want a smoky backdrop. Just imagine your model emerging through thick layers of smoke to reveal a brand new fashion line.
For this type of scene, you’ll need to use DIY fog juice along with your homemade machine. An average temperature room is ideal for keeping the fog nice and light so you can create that misty and mysterious vibe.
A good alternative is, of course, to use colored fog cakes or colored smoke bombs. These decorative devices work a lot like traditional war flares. They’re set alight to create bright-colored smoke backdrops.
While colored fog bombs are a good alternative, they can be hard to come by and are usually short-lived. The amount of fog produced is also usually limited while a fog machine will give you a consistent supply of smoke.
The basics you need for any of these effects are a thick and constant supply of fog and an ideal room temperature so the fog will linger for longer before it starts to evaporate.
How do you make low lying fog?
To make the easiest low laying fog, you need to find a way to chill the fog liquid of your ground fog machine. This makes the liquid thick and dense, so it stays low to the ground. However, a ground fogger is also a popular store-bought option if you don’t feel like making it yourself.
Chilled fog machines like dry ice machines, compressed liquid CO2 fog generators, liquid nitrogen fog smoke makers, or liquid air fog devices naturally tend to produce low-lying fog and you can keep the fog close to the floor by cooling down the room temperature. As the temperature increases, the fog will start to lift and it will start to clear up.
We hope that you had fun learning how to make your own DIY fog machine, but if you’re not quite ready to take on this type of experiment or if you’re looking for a device that’s already built and designed to produce lots of fog without any effort then you should have a look at some of our other guides.
On GetFogMachine, we strive to help you find the best fog generators and we offer terrific tips to help you make the most out of your fogger.
