This is the best description i've seen. Thank you!

Awesome breakdown, Eric! I used this effect for a show earlier this year! The actor had to create the fire on stage with a clay pot and logs. I placed metal paint can, with holes in the side, in a slightly larger Tupperware container with water, and then placed that into the clay pot. Ultra sonic pond foggers were placed in the water and halogen lights were placed in the paint can. The heat from the lights drew the fog into the can and made it rise quickly. I used yellow and orange gels (you're right about red haha) on the lights to give it that nice fire look. The only drawback was that the show was in a lab theatre, and the scene became very quiet. You could actually hear the foggers making splash sounds. I don't think the audience connected the dots though. :P

OMG this is the best DIY video ever!!!!!!! My family and I run a haunted house/spook house every Halloween. I have been searching for a safe way to have a burning witch screen for a VERY long time. I can't wait to try this! Thank you for the info!!!!!

this is actually very amazing.

Wow, that's awesome! Thanks for sharing!!!

Great I love it!

I like your ending pun!!!😂😂💙

I'd love to use this for an art project. Thank you! 💜

AMAZING

This so amazing my face was like 😲😲😲😲 the whole time

Thanx for sharing. It's awesome! I can't wait for my book to arrive! I'm planning to make one of this and simulate flame level by controlling light's intensity with DMX dimmers, according to the movement of the performer, read by a mobile phone attached to his jacket in an internal pocket. Do you think that changing the intensity of light will give the impression of flames raising and lowering down?

safety 1st humidifiers, but wht modle?

Could a similar approach be taken to create a effect of mist coming off of a lake (using more blue lights)? I’m actually needing to create the illusion of light reflecting off of a lake.

What kind of humidifiers are those? Every one I find does not have the same fog output as yours.

Woooooooooow

whata the name or brand of the humidifier you used

The holes on the pipe, howbig was urs and how far apart

Looks great! I think it would look even more realistic if the lights flickered a bit, easily done with LED lights and an Arduino. Anyway, I'm looking forward to your new book.

We've done this effect with a few LED strips that could have a bit of a flicker pattern programmed into them, so that did give a more realistic effect.

Hey Eric, that fire looks amazing. Well done! I've been tinkering with a similar project and really trying to miniaturize the mist/ light unit as much as possible for a tabletop version. It seems you just need air volume for a good mist though. Any suggestions making this as tiny as possible?

@@Midnight_Immortal thanks, I did try talking one of those apart to try to change the airflow pattern of the mist. Then I bought a fish pond mister which worked a bit better, but still not perfect.

Do these work well outside?

The effect looks really great. And I really like the idea of using the pipe in order to lower the source of the mist because I plan to use something similar in faux fireplace where the installation needs to be as low as possible. But I have one concern: does mist condensate into water inside the pipe before reaching the exit, and if does, how did you solve it? Thanks!

@ricardoscholz

Hi. On my experience, yes, mist condensated into the pipe, and also in the tube holes, blocking mist after a while. I solved the problem using a pipe for each umidifier (single individual mist exits) and avoiding "U" shape paths in the flexible rubber hoses, so water went back to the umidifier instead of accumulating in the bottom of the "U". I made a comment in the main thread with more details. Good luck.

Love the dad joke at the end..)))

where did you put the fan, exactly? you said it was above the fire to pull it up. it is hard to picture, can you explain. also, would you reconsider republishing so we can see it?

Hi again! I'll leave here some "lessons learned" from my experience with this effect in an opera. The idea was to replicate Eric's proposal, but we had to make some changes on the way. Our setup used 8 umidifiers (G.tech Allergy Free Hm 3L), a vertical fan and a PAR 64 LED, with a Kinect or mobile phone attached to the performer to controll intensity through a software. Fire was comming from a hole in the theatre stage floor, and all fire equipment was placed bellow the stage floor. On our first prototype, the 6mm holes in the tube allowed water to condense and block vapor after a while. We widened them to 8mm, but just got more time untill the problem happens again. So we decided to use individual flexible 1" rubber hoses (one for each umidifier), pointing up directly. Also, condensed water was comming back to the umidifiers through the hoses, so if hoses had curves in "U" shape, water would accumulate in the bottom untill the hose was obstructed and then mist would pass in "pulses". Solution was making sure the hoses would let the reflux go straight back to the umidifiers. The interactive effect of flames rising and falling was best achieved by changing fan speed, instead of light intensity. The downside is that changing fan speed has a natural delay, due to the time taken to the fan engine to speed up and to the wind to move, while light intensity changes are instantaneous. Also, we used a light flickering effect, varying light intensity around a center point, to try to give the fire a "candle" effect, but this must be used very carefully, as too wide variations may look or feel weird. Finally, the fan proved to be essencial. When we tested without a fan, the water mist tended to spread close to the floor. If you guys want to see the results, ask for making-off pictures and/or explanations, or use the algorithm we used to make the fire interactive and/or flickering, go to ricardoscholz.com/en/a-compadecida . Thanks to Eric Hart for the video explaining the original idea!

When I saw such decorative fireplace, I understood how to do it. And my idea was very similar to yours. I don't understand why they are so expensive if they are made from cheap tech. Prices can easily achive $ thousands.

Any thoughts if a fan can be placed BELOW the water mist distribution PVC to blow the mist upward? I need an effect in which equipment needs to be hidden below, but not above the misting PVC pipe. Thanks!

I used a fan below the mist distribution, blowing upward. It wouldn't work for me without it. However, I abandoned the PVC pipe with holes, as mist condensed and blocked the holes after a while.

How long will a tank last minutes wise? Sould these go for 45 minutes or possibly an hour. My band wants to use this as a staging effect.

Hello, may i have a question? Can we replace the humidifier with dry ice for short-lasting fire? I am actually need to set the whole stage on fire :'')

@burntcoppery

Жыл бұрын

you should be able to - theatrical haze (less toxic and easier to breathe through than dry ice) can be piped reasonably easily. I've tested the above effect just using a basic home humidifier and a pipe with holes drilled in it. The only problem is it takes longer to build up enough to light and longer to dissipate than steam - you'll have to get the fans at full blast.

I haven't tried it, but it may be tricky since the humidifier needs to remain fairly level and steady. The water will slosh around a lot if it was in a costume. But again, I haven't tried it, so you may be able to solve that challenge.

What is the urgency of creating such Maya effects....

You can buy a ready made and ultra realistic fire already made but they are a few hundred bucks, but where is the fun in that lol I have a bought Metal bsket that is now fitted with fire led bulbs and the effect is great, behind that I have a cheap 23 flat tv with dvd player built in with one of those log fire DVDs, it looks fantastic AND has the wonderful crackling sound, very relaxing. I want to add smoke with a cheap pond fog maker but Im stuff trying to keep the water vapor away from the TV

fog and haze fluid is not as dangerous now adays.

So this is what SpaceX use for their rockets

Well, you ruined it with that lame pun at the end, otherwise, I definitely want to try this.

Really? Didn't make the obvious joke and call it a humidifire? Lol
