Mighty Mini Fog Maker




About: Tinkerer, hackster and prankster. Hit me up on Facebook: https://www.facebook.com/kipkayvideos/ Thanks for checking out my Instructables!

Here is an easy mini fog maker that produces mighty results!


Step 1: What You Need

1. Coffee Can (large size)
2. PC Fan - I used a 60mm
3. 9 Volt Battery and clip
4. Hose. I used a section of pool hose
5. Dry Ice and water

Step 2: Prepare the Fan Blower

Lay out the computer fan on the top of the coffee can and draw a mark around it. Cut the top just inside the mark. Using hot glue or other epoxy, glue the fan to the top with the air flow facing inside the can. Add the 9-volt battery clip to the fan.

Step 3: Add the Hose

Make a mark at the top of the can using the hose as a guide. Cut out the hole in the can using whatever tools work. I used metal shears and then a Dremel to round it out. Squeeze in the hose or use hot glue to secure it. It should be a tight fit.

Step 4: Make Some Fog!

Break off a chunk of dry-ice. Heat some water in whatever method you prefer. Plug in the 9volt battery to the clip. Add the hot water to the can, drop in the dry-ice and quickly cover the top.

You've now made some mighty fog! I hope you enjoyed this Instructable!

    Does the can have to be metal? I don't have a metal one.

    It's possible using a CO2 fire extinguisher. There are some videos on youtube.
    But this method is not much effective and more expensive than buying dry ice. But I understand, it is sometimes hard to find some in your area. And these extinguisher are almost in every public buildings ;-)

    Where do i place the PC fan on the chiller container? I really want to make my own but what i put inside the container is what i do not understand.

    So, after putting holes in both ends of the chiller container, what else do i put in the container apart from the ice ?

    I will be happy to hear from you soon

    Thank you

    How long does the fog last ? (yeah, it depends on the amount of dry ice but still...)

    And if you can't get dry ice use fog fluid but you will need to add a very powerful heater to the project.

    You can get dry ice from almost any local store. They get it when they get big shipments. I should know that's where I get my dry ice and most of the time it's free because they don't use it.

    I don't think it's generally available here in the UK. I've never been able to find it for sale, but compressed CO2 is so commonly available in so many different sized cartridges and cylinders that I doubt t would be economical unless you were using a LOT.

    I purchased a 5lb block at our local Publix which is a popular supermarket chain. YOu can also ask your butcher or other food location that receives frozen foods.

    this really good you could use this for disco smoke if you cant be asked to buy a new and sealed smoke machine.

    but it would have to be weaker if it would be for disco stuff
