Hi All.

I was walking through a gadget shop and saw a small 6 inch witches pot pumping out the coolest smoke that fell to the ground just like Dry ice.

Said to myself… no way would they be that stupid to put something as dangerous as Dry Ice on display so I decided to touch it to see if it was cold.

Nope… it was warm, and better again. It was plan water.

So how did they do it smile Seems you can buy a Ultrasonic Mist maker these days. One small enough for some funky fun, or one big enough to float in a pond.

This is what a 5 Head Looks Ultrasonic Mist maker looks like this turned off and out of water.


And this is what a 1 head version looks like in use. The 5 head would produce obviously 5 times more mist and is recommended for outdoor use



A one head can cost around 20 Uk Pounds, and the top of the line 5 head ourdoor can cost 100 UK Pounds. They come with the LED lights built in too.

Thought you all might find this interesting.

Regards.
Sharp.

Hi Guys.

I’m getting one from the UK, but after a few days searching around the net, my advice is to pop “mist maker” into google. It will give you hits to countless online stores selling everything from single head mist makers right up to 5 head ones with built in LEDs.

There are lots of different combinations. For messing around in the house, a single head would do the trick. But for some serious levels of freaking cool mist, you’re going to need the 5 head system.

These puppy will float on their own and shovel mist out by the bucket load.

Regards.
Sharp.

That would be amazingly awesome, but since it's water, wouldn't it condense all over the ground over time and mess up wall plugs and paint?

Also, just how much mist does a 5 head make? What about a 1 head?

I do a haunted house every year, and the best fog you can get is to buy a party fog machine from Party City or Target, then get a small cooler, make holes on both sides, and stick ice in the cooler. Then put chicken wire over one hole and the nozzle of where the fog comes out of the fog machine on the other. The ice cools the fog, making it stick and last five times longer, as well as staying on the ground primarily, which is alot cooler. I considered using this effect for Found, but it just didn't work out.

Hey thats a fantastic piece of info. I'm in the UK , where are you getting yours from ? Are they available from high street stores do you know ? I'm inpatient lol Plus i know my girlfriend would love something like this and shes back from uni weekedn after next so need to get an indoor one pertty sharpish. Cheers again for the great info buddy. Oh yeah i could do with an outdoor one for a film idea I have brewing too. Smoke machines you can pick up at Woolworths or maplins in the UK for a cheapish price. I did some work with a photographer friend of mine a few weeks ago and she used a woolworths smoke machine to create light beams in a basement setting, it worked really well.

I've had one of these for about 2 years. Someone bought me a 'fog lamp' which was a bowl of water that lit up and made smoke. Do you know how it works?

I bought one just like that for $20 at walmart. I was thinking about buying one with a built in cooler like This One. It will keep your fog nice and low, and it's affordable. How did you connect the Cooler to the Fog machine? What size of a cooler do you use?

I just ordered a single head one with built in LED’s from http://www.aquatics-online.co.uk

I’m starting off with a single head one because I’ve decided that if I like what I see, then I’m just going to splash out and just buy the biggest one you can get. I would also have use for a single head one for some photography anyway.

With that said, the largest I’ve seen is a 10 Head System that eats 3 litres of Water an hour. It costs just over 200 Euro. I will probably buy it, but not until I’ve played around with a single head one here for a few days.

Regards.
Sharp.

We use both the Walmart fog machines and 2 of the fogger you linked. Because of the awesome scale of our annual haunted houses (which, yes, goes through/around our entire house) tons of blacklights, fog machines, strobe lights, and hundreds of yards of heavy-duty black plastic are a must.

How funny of this topic to pop up right after my purchase of a fog machine. I'll pass on the knowlege I've reaped from my research on the subject razz

Wanna know about Fog Machines?

Plans for the cooler mechanism Ben mentioned

You can find cheap fog machines at Wal-Mart. They most they cost are 20 bucks. Seriously, i bought my machine at wal-mart for 20 bucks, went online and found it at cheapest for 60 dollars. Dont buy online. You can also run fog through pipes to get it around... but remember, low lying fog wont go up through pipes.

Hi guys.

Does cooling the smoke from a fog machine really work ?.

I can’t see how it wouldn’t return to room temperature after a few sections of being released.

Kind Regards.
Sharp.

Miker: I have not built/tested one yet, but i plan to for this upcoming halloween. I want to have the fog spill down the front of my house, for a house of doom type effect.

Sharp: It does work. It eventually heats up and dissapates, but it cools it long enough for the effect.

Sweet… Whish I had known that before I sold my one.
I had a very high pressure one that we used to use gigging. Believe it or not, I actually sold it to the local Airport in the end because it was so strong. They use it now fire training exercises. My bro works there.

Because the fog is a (fairly, with respect to its temperature afterwards) cool liquid before it gets heated up in the machine and becomes fog (which eventually dissipates through the air because by heating it you are essentially vastly speeding up its evaporation), turning it to its vapor (fog-like) form, then re-cooling it effectively slows down its evaporation; so much so that it condenses the fog; making it heavier, wetter, and longer-lasting. If you use dry ice blocks instead of regular ice in the cooler, not only will the fog thicken due to the colder temperature, but you ultimately get the whole dry ice effect in collaboration with the condensed fog. Be careful, though, chilling the fog too much will just revert it back to its 'pre-put-into-the-fog-machine' liquid form, which would just be a waste of materials.

So, ultimately, yes, the technique does work.

Thanks for the tips guys. I didn't even think of using dry ice. I will try it as well this halloween. Tell me hows yours turns out timmy.

Do you think this will work?

*Cut 2 holes in both sides of a cooler.
Fill the cooler with ice/dry ice.
Put fog spray nozzle up to cooler hole.
Turn on the fogger.*

Would I need to do all the fancy work shown on that site or will this work ok?

The piping on the side is there to keep the fog in the machine. not from going all over the place then exiting. And you NEED the chicken wire tube inside the cooler, or else the fog wont be able to go in/ leave the cooler.

I'd suggest making a cylindrical mesh or wire that keeps ice from blocking the path of the fog through the chiller. This way you have all the cool of the ice while still retaining the power and speed of the original fog.

Thanks ben. I'm going to make one with a wire cylinder rather then the crappy thing I made last night out of wire hangers and string. It worked ok for a test. Melting ice blocked the pathway of the fog so it slowed down the output. Thanks for the tips.

Sorry to post on a rather old topic, but i finally got off my butt today and started to make one of the fog chillers. I took a big styrofoam cooler and cut two holes in the end, like you should. I was looking for some mesh wire, but i couldnt find any, so i used a large section of PVC piping and drilled 90 holes in the top of the pipe, to let the cool air sink into it, and about 10 holes on the bottom to let any water that may end up in there escape. I then took this powder stuff that turns into like rock hard something after it dries, and sealed up the ends of the box with that. For ice, i thought that you could use a plastic shopping bag, like the ones you get at the supermarket, and fill that a little bit with water, and freeze it, sort of like an ice pack. I've got two in my freezer right now, so i hope they turn out good. I'll let the putty dry over night, then tomorrow ill paint the whole thing flat black to diguise it in the night. I'll post pictures tomorrow, as i just got through watching the Sixth Sense and would rather not go down to my basement smile.

(i got the DL24L- only £19.99) So i will see what it is like.

Just a quick question -

How much condensation do these water-based mist makers create? It's just I'm currently helping to plan a shoot in a functional TV studio, with hundreds of thousands of pounds worth of equipment, and I need to know how safe it would be to use a mist machine rather than hiring out a proper smoke machine. It'd be massively cheaper for what we need it to do (as we only need a small ammount of smoke from one or two points - nothing major).

Any help would be majorly appreciated smile

Cheers,
Arktic.
