View Full Version : Fake Fire with Water Vapor and LED's

02-03-2011, 07:07 AM

Hey everyone,

I discovered this article this morning while doing my usual news reading and I thought this would have a very practical use for the haunted house industry for those able to build a similar system to recreate a realistic fire.

The system uses a fine mist of water vapor and LED's in the logs to recreate the illusion of a moving flame and smoke. I think it looks incredible and would be great illusion by to recreate. Let's see if anyone has ideas on how to build a cheaper similar system that pulls off the same effect. You can find a video of the effect on the article page.

That phone doesnot look real to me!
Somebody must have "built" it.
I might approach this tecnical problem by just building a phoney phone out of a solid steel block, then throw it into a real fire. hahahaha! (Low-Temp fire, of course)
Just like satan's phone!

The phones ringing Jim! Its just nobodys home! LOL! This looks pretty cool. Never heard of one using a mist. Looks realistic.

i mentioned in chat the other night about the electronic cigarettes that let you blow water vapor "smoke" Neat use.

That's a good youtube vid. I think this is a much much better illusion to use then the fake firepot with the fan blowing the cloth over orange light.

This would be great to create a retort ("oven") for a crematory scene.

Cheaper ideas? Well, most of the ones I've been looking at seem to work on water vapor- and there are clips out there showing people experimenting with just that sooo...

I'd say use a 'vaporizor' humidifier- because it's actually steam and will rise higher than cold water humidifiers and ultrasonic fountain transducers (they make a nice low fog tho!). The real trick would be on how to 'train' the vapor and direct it to desired location without losing moisture along the way (anytime steam contacts a surface- like the wall of a pipe- it's going to condense back to liquid- especially at the relative low temp we're talking about here) and also control its velocity. I also think using fans on the steam is going to knock a lot of the moisture out of the air as it passes through the fan blades...

So just off hand I'd say get a quality home vaporizor humidifier ( or commercial if you have the dough), set it below your 'fire pit' area- figure a way to distribute it with as little surface area as possible, and light it with colored lights. I was going to say - use LEDs to light it, but it may be a better idea to use incandescent because of the added heat they will give to the air and may promote air movement without the use of fans. In fact it may help to put the vaporizor in a box that is heated with heat lamps or similar to really get the air flowing. OBVIOUSLY we're talking about water and electricity here... don't be a fool- do it right- use a GFI amongst other precautions.

I think the added heat would also cut down on residual moisture problems as well.

At least your monsters won't have to worry about pesky dry skin irritation...
