For a smaller chamber you can use an ultrasonic mist maker, they just require water and electricity. You wouldn't think a small mist maker would work well, but I think the low pressure center of the vortex helps bring out the fog.
That's what I was thinking as well. Wonder if you could get several of them for the big tornado machine? I can't imagine the residue from those fog machines, I've noticed white mineral dust from the ultrasonic humidifiers, let alone atomizing oil or glycerin in the air.
@@Dan-yk6sy That is some hard water you are dealing with.
Yeah with distilled water. It would take several high power ones, but would leave only water.
@@Dan-yk6sy With decent juice there isnt ....much.... residue. Then again, Ive mainly used them in themed attractions ( from little 40w cheapies to 1500w ones with dmx and stand alone brains) not an plexi box, but there is a VERY stark difference between walmart fog juice and something like frogger juice. Especially if you use a more hazier or stringier fog (hazers are for lasers, and strings are for like flowing through something like fence stakes, makes long wispy tendrils. From what Ive been able to get out of the guys from Frogger at conventions is the fog characteristics has to do with how the glycol chains form after the water flashes and the steam 'fluffs' the oils into the air and carries them out of the machine), compared to something like 'bog fog' which is the thick long lasting low to the ground stuff. You can use old ecig cartridges for mini foggers, just add a bit of airflow and you're set. I use an old vape pen with some fog juice for visualizing my laser demos (more science-y diffraction and interferometer stuff). Otherwise, yeah, absolutely use distilled non-mineralized water. The ultrasonic disks pulverize the water into droplets (basically cavitate-shove-cavitate-shove etc) so anything in the water will just fall out and cake on the disks. The good news is there are models with replicable disk sections (they're just held down by a ring retainer onto the contacts). So if they get too scummy you can just order a bag full of replacement disks instead of replacing the whole unit. Oh, side note: remember to run vinegar and distilled water through your fog machines before and after use before storage. The last run should be just water until it stops smelling like vinegar. Gets all the leftover crap and crud out ;)
This idea has me thinking of the possibility of using it for wet flow analysis of cylinder head / induction systems, on a flow bench. I realize it wouldn’t be a exact analog, for differences in characteristics, between fuel and water, but think it may provide a demonstration of the general behaviors of aerosol flows within specific port configurations.
You could place this just about anywhere in public, charge money to enter, and in a few years retire! Very cool!
It sounds easy, but trust me, keepin' a dozen 'nados in line a'int easy. Most of them are all screwed up, been turning sticks since they can remember. As the good Presenter has demonstrated, all they really need is a stable home, uplifting motivation, and loads of sheer.
Either that or set up a science museum with all of his creations and charge for entry
I would enter👍
Retire? The master laughs at you. Ha! 😁

I like the modular panel design! I hope more people play with the idea. Nice work. I have built a number of tornado machines for a local science center to loan to schools, and a large permanently installed machine that produces a 10 foot tall tornado. These used ultrasonic vaporizers to produce the fog, and they performed very well. The small machines (producing a four foot tall vortex) worked ok with a household sized ultrasonic vaporizer. The ten foot tornado used an industrial unit with eight transducers, fed with tap water run through a filter and DI bottle so it ran continuously without needing attention. These machines didn't use clear panels but instead used four hollow posts that each had a row of holes along the length to form a set of air dams which both gave the rotational motion and helped exclude ambient air currents. This allows people to simply reach (or walk) in and play with the vortex. One other tip: The vapor source should be underneath and coupled to a flat floor with a perforated central area (like a perforated pizza pan). Having a large stockpot or humidifier just sitting at the bottom causes turbulence that disrupts the laminar incoming flow and makes the vortex less coherent. You should be able to see that the vortex has a hollow core!
Minor correction: when an ice skater pulls in her arms, she is conserving angular momentum, but gaining kinetic energy- pulling in her arms against centrifugal force takes work, and that work goes into increased linear speed. (if you refuse to work in rotating coordinates, the velocity vector of her hands is not perfectly perpendicular to their acceleration while they are moving inwards, so they gain speed- but it's cleaner to just work in rotating coordinates) Sorry to nitpick, but the increase in pointwise velocity as a tornado contracts is important to the destructiveness of the phenomenon. love your videos!
I still remember my 7th grade science teacher back in the 90s doing a tornado demonstration showing some similar aerodynamic effects, only he used fire to create the tornado. The demo required only an empty coffee can with a small piece of cotton cloth soaked with something flammable (can't remember if it was lighter fluid or kerosene/lamp oil), all set atop an old phonograph turntable. The updraft created by the convection from the heat rising, along with the rotation from the turntable, created a stunning twisting fire column that of course as kids we all enjoyed watching. And since it was literal fire, the tornado was self illuminating and wasn't dependent on humidity of the air to condense water-droplets so it could be seen; in-fact the effect looked even better in the dark when all you could really see was the whirling tornado. Thanks Tech Ingredients (and my old teacher Mr. Wolf) for making science fun and interesting!
okay as you are discussing the foggers, there is a very interesting oscillation of the vortex going on behind you. id love to see more of that
From a videographer standpoint, i hated that he was standing right in front of the most interesting part.

When I was a kid, I stared at the little tornado chamber at the Detroit Science Center for as long as I could. This takes me right back to it. I know most people have rejected it as balderdash, but have you ever looked into the vortex engineering by Viktor Schauberger? Nobody has ever duplicated his work (and his son and grandson devoted their whole lives to it), but there is great power in vortices, much of which he observed as a young forest warden in Austria. Interestingly, we had a cool mist humidifier for a while that had an almost exact (plastic) replica of a Schauberger whorl-pipe that drew up water axially before expelling it radially onto a series of diffusers....
Schauberger had a very esoteric understanding of nature which many have sensationalised and misrepresented. He had a very solid understanding of fluid dynamics and some interesting ideas about energy and it's production which came from that understanding. It's hard to tell how many of the claims about Schauberger and his work are true but the fundamentals of his work would be worth looking into.
I have a mechanical engineering degree and you explained Bernoulli's principle better in the first 3 minutes of this video than in my entire education. Thanks! That one's been so non-intuitive for me this whole time, but the conservation of momentum explanation makes perfect sense.
I think youre just not studying properly.
You guys are incredible. The work going into each show is fantastic and I always come out understanding principles better than before. Excellent explainer.
I love watching these videos with my 5 year old. He sat here fixated the full half hour. Thanks so much for making such an amazing channel.
Wow!
I wonder if you could "harvest" the static from all that air moving across the plastic film so you could have lightning accompanying the tornado.
This is definitely impressive! People don't commonly understand the structure and dynamics of a tornado. I'm going to share this video with a local Meteorologist who is very interested in science and weather dynamics.
Please do!
Our friendly neighborhood Jedi scientists are back! This is AWESOME! And mind you, those jedi robes fit you rather well. Surprisingly well. You do, in fact, look like a wise jedi master.
I understand his choice. I'm in my 60s, and the first Star Wars movie was released when I was still in high school.
Eh?
well.. maybe more like a Walmart jedi master
Jedi is fine but when he stepped into his temple the first time I half expected to see Leonard Nimoy’s face when he turned around 😂
He showed us all how to use the force
5:14 it seems so obvious when you put it this way. I feel like we take our everyday context, like air pressure, for granted and that can lead us to incorrect mental models. Explanations like this are the perfect way to correct that. Yes, Science is wonderful!
If you watch videos from How Ridiculous, when they drop a big rubber band ball with a small rubber band ball behind it, from a drop tower, you can actually see when the smaller ball tries to move out from behind the large ball, it is deflected back to the area behind the large ball. It's kind of like the demonstration you did here with the ball in the air stream.
Beautiful video and beautiful build! BTW- For those who would like to create beautiful underwater tornadoes on a tight budget, you can do so by filling a tall jar or cheap plastic bug terrarium with water then add a layer of ultra-fine grain aquarium filter sand on the bottom. The finer the grains of sand the better. Regular playground sand is too heavy and will not work very well. Ultra-fine sand has just enough weight to easily be lifted and fall back down gently. My local PetsMart store sells bags of ultrafine aquarium sand and small bug terrariums for cheap. The tornado itself can be easily produced with a cheap, battery-powered coffee milk frother that uses a small, spinning coil of wire to froth milk (create milk foam). Simply lower the spinning frothing coil into the top of the water. It may take a few moments, but a vortex will form that will eventually reach down to the sand and will start to pull grains of sand all the way up through the vortex and spit them out at the top like a real tornado. Tornadoes produced this way can look very, very realistic. Total cost of all three components is about $15 US dollars. Bags of ultra-fine sand usually contains a lot of dusty particles that will cloud the water. If the water gets cloudy, simply do a few water changes. You can also “steer”, or guide, the tornadoes around the aquarium by moving the frother. In one of my science classes I used a 10 gallon aquarium with a 1/2 inch (2.54cm) layer of ultra-fine sand at the bottom and handed out a bunch of cheap milk frothers that I purchased from Walmart for a few dollars each. We had as many as 6 tornadoes being produced at the same time in the aquarium. The students very quickly learned to start attacking each-others tornadoes by moving them around the aquarium. We called our new game: ‘Tornado Wars’. PS- I’m jealous you can wear pure white in your shop. Two seconds in mine and it would be incredibly off-white. 😭
I dont believe thats a Tornado machine. I think its the start, and the excuse, to build a sky-diving machine. You people are crazy and i love it
I consistently delay watching your videos and did not know why until now. They are like a fine whiskey, meant to be enjoyed in the right mood and not gobbled down as fast as possible. You just keep surprising me with new and interesting things, ever expanding the appreciation for practical scientists and engineers. Thanks
Best explanation of Bernoulli's principle I've heard yet!
This is the epitome of what beautiful minds can achieve, for a weekend project, when they have the time, the space and the means 😊. Eric you never cease to amaze me.
Indoor tornado experiment has been one my favorite topic to search though there aren't much quality video about it on KZhead. and when i see you made one, my heart is racing from excitement 😂
One of the best public facing science/engineering/tech communicators on the planet imo. Thank you for sharing your work with us!
Wow, thanks!
I personally like the way the walls self stabilize once you stop the big intrusion of air from the door
I have never been disappointed in watching any of your videos, in fact I have learned a great deal by watching them, some more than once. Many thanks for what you do ! Longtime subscriber…
The fire nado is pretty cool as well during large forest fires. Meteorology speaking the structure of a supercell has a lot of contributing factors such as the beavers tail forms with certain inflows thus adding to the sheer bases form rain free and shafts for rain this is a great example of using the doors to help create the variable winds that are actually occurring out in the field. Great job kind sir!
All tornadoes start horizontally amazing explanation and even mentioned this awesome!
"Tornado Robe"? ... May the force be with you :D
This was one of your best episodes, you explained lots of interesting science in a succinct and lucid fashion. The chamber is nice too. Thanks!
I have to agree with some others that this was not only a really cool (but surprisingly simple) project, it was one of your best "science lesson" videos, too!
I love your explanation of the ice-skater's conservation of angular momentum. Most people assume that everything is moving "faster", which you correctly stated as not being true. People get this wrong about orbital mechanics, too.
If the levitating ball setup weren't so power-hungry (and loud), this would make an amazing interior design element, instant conversation-starter and tool to get especially kids interested in science... now all we need is a magic fan.
Love these projects, and I always learn something new. It's been fun watching from way back when it was about banana liqueur, diy speakers and more.
I've been subscribed for months or years. Great channel, great educational content and great speaker. Thank you for your videos.
Such a nice description of Bernoulli principle. ❤
The equations and explanation of them. Is a favorite love from your channel.
Great video as usual. 1 - its interesting how your presence inside the chamber disturb the flow. See the perfect and mesmerizing flow when you are outside. 2 - if I could i would place the dry ice on top and the fan on the bottom to see the difference. Cheers.
I have been following this channel for a a couple of years. This one of my favorite videos from this channel. Fantastic job.
Wow, thank you!
I would love to see you explore using additive manufacturing to build a subwooofer. You can make the subwoofer easier than ever before and the math of subwoofers is wild. Fantastic video.
Again thank you for the awesome, informative demonstration.....
Yo mate, your videos are one of the few ones which I have been watching from start to end, without speeding up. I enjoy watching and learning new stuff too. Very nice explanations and showing each new thing step by step. Keep up your good work 😃
Thanks!
Your videos are so good. Definitely my favorite science channel. Most channels arent advanced enough for my liking.
I built one of these ( much smaller) with my Dad when I was 12 (1982) for the school science fair. Just used hot water for steam, worked great.
You guys don't post often, but I'm early for this one! 👍👍
The production value of these videos are getting better and better with every episode. Great vid
I'm continuously amazed by your effective and inexpensive designs
Absolutely fantastic video, thankyou!
In the 80s, I was a SkyWarn spotter, and saw all kinds of effects in the winds and clouds. And once I rode out a developing tornado in my 3/4 ton pickup truck, that was an eye opener!
Yes sensei! Another awesome video!
Outstanding visualisation!
Excellent. Keep up the good work!
Who else was shouting, Its behind you. Those resonances were the best bit. Amazing work as always and thought proviking.
I wish you had measured the wind speed in places but never the less I love your channel and thank you for sharing your knowledge with us.
Awesome work as usual boys!
If I remember right, when we saw a demo of this in elementary school (40 yrs ago) they used a pan of water on a hot plate at the bottom, and no fan. Not as impressive but truer to the actual formation of a tornado. Things have to be just right to get it to work but the vapor funnel is actually water condensing out of the air.
I love this channel so much.
😊 Your B-roll game has improved so much. Great work!
Very impressive. Thank you for that.
the Dry ice finishing to evaporate looked realy cool. shock waves going up and down the coloumn.
So awesome.. still hoping to build the speakers you built one day ! 😀 The tornado chamber is next!
dude you explained the reason for the speed of sound SO EXPERTLY and so clearly. love it
This channel never disappoints. What a fascinating video.
Awesome stuff. It was fantastic to see you approach some of the same concepts I've learned from Dr. Reed Timmer, just through a different lens.
That uniform is channeling some serious WEF energy
Thanks for this video and information guys. Cured my boredom.
This looks really awesome
that was a pretty cool thing you built there, loved it sure it was a crude example of how a tornado forms and works (without the strong wind force behind it) the visual was pretty awesome :o) 👍
Nice sleeves, they’re real big. Another next level video 🙏🏻
The vortex form at 25:55 is really, really cool
The only thing missing was a small fire source. Heck, try several. A little wood, alcohol, gasoline, what's that liquid that burns green? Oh, of course you don't want to burn up that fan... Hmmm. A few yards of ducting, maybe? Cool video. I very much enjoy your approach to science.
Woahhh you guys went all out for this one. Incredible work!!
Glad you liked it!!
Amazing stuff!
Great video, great work, awesome
Having sold vacuum cleaners,(as a young teenager in the seventies) I developed the skill at subtly moving a business card from nozzle to another. When making a sale I would, when the opportunity arrived, place my business card on the customer's old vacuum, then lift it off with mine. Not mentioning that I could easily do the same thing in reverse. I recently tested my skills to get my pick of machines in my construction. I just explained that I was giving the stronger machine to the other guy. A piece of sandpaper proved it. The value of a properly misspent youth is proven yet again.
Thanks for the wonderful demonstration and explanation of tornado formation processes! It looks like the vortex is rotating in the same direction as the fan. I imagine If the panels were adjusted so that the vortex was rotating in the opposite direction of the fan, the tangential velocity of the vortex air stream would be more effectively captured by the fan blades and resulting a much higher air flow, fan loading and stronger vortex.
your video production has really come a long way, i'm amazed you're not at a million subscribers by now
Love these! Small suggestion... if you have an electro-mechanical device... even if its operation is apparent, like a fan... put an LED on it to indicate whether it is powered or not. I think this will increase production value for only a small addition.
The Force is strong in this one
Definitely cool to see, and probably feel feel at the center of the vortex. Definitely an interesting video.👍👍
I can’t believe you guys don’t have way more than a million subscribers yet. I love your channel. Thank you
It's a bit too much for the folks with a 10 min attention span. I'd like to think that in some small way, having a quality audience pushes them a bit higher but I agree that it would be nice for them to be more widely recognised.
Brilliant video! Good luck on 1M subscribers, Mr Ingredients and Son.
I'm a bit of a tornado nerd, and this vid was a great description and depiction of how they form and operate. Thank you!
Glad you enjoyed it!
Another cool video by Tech Ingredients! My only complaint with you guys is that you don't produce more videos more often! Probably due to costs constraints in both dollars and time... you know... reality! Thanks for another highly entertaining video!
we must be from around the same Era 😀 I remember as a kid back in the 70's, going to Sears or Montgomery wards with my folks and seeing the vacuum cleaner displayed with the ball floating. it also fascinated me, I remember sneaking back to the display while my folks were distracted with looking at sometime else, and they always knew where to find me when I wandered off 😀👍
great vid again!
You just explained how sound travels in a way I could wholly grasp, thank you, and it took you like 15 seconds, lol.
Good Explanations! 🌪️
watching your demo about air pressure in the beginning made me think about those things you attach to your hose to add chemicals or something like an airbrush for paint. i already knew how those latter things work but i never really connected them in my head before or realized that it would work in open air like that.
This looks so damn cool. Kudos to you!
I love the cheese almost as much as the cool science explained so clearly. Thanks for yet another great show! I'll have to replicate this for Halloween next year, if not sooner. The noise is the only issue; I wonder if concealing the fan elsewhere with ductwork between would dampen that noise enough not to interfere with a social event. hmm...
That was awesome. The tornado robe is reminiscent of the one Neil Peart was wearing on the back cover pic of 2112. I find favor with same lol. Still my all time fav of yours was the cloud chamber for sub atomic particles. That was about the most amazing thing but on many levels from construction to theory to visualizing the universe in which we live. I think about it often.
this is so awesome!
Just when I thought that the videos on this channel couldn't get any more spectacular, these guys built a walk-in tornado chamber. And then you explained how it was not at all difficult to build. Suggestion: Can you try to float a ball or balloon in the tornado? I would _expect_ that not to work because the fan is at the top, but who knows? Or you could always tie it down.
Sometimes in the early morning over a still pond, a few minutes after the sun hits the surface a frantic mist appears over the water. The amazing thing is six or twelve foot tall mini tornadoes about four to six inches in diameter.
Sunlight photoionises the surface of water (see Gerald Pollack) which creates water vesicles (via sputtering of sufficiently ionised bodies) that approximate a dust/vapor plasma. It so happens that both the vesicles and the Earth's surface have a bulk negative charge causing the levitation of the droplets and water vapor. (again Pollack). What does get interesting is that aerosol largely acts like a gas, and since the droplets have a bulk charge, it acts like a gas plasma. The vortices you see are a result of Marklund Convection, the formation of plasma filaments (very common in plasma experiments). The rotation of the vortex is induced by the Lorentz Force. If the vortex were powerful enough, like that of a hurricane, you'd see that there's a concentric and counter-rotating shell around the inner cone. This counterbalances the spin, and the current of the vortex. Given the difference in radii, and volume, it doesn't need to be that (charge) dense, thus diffuse and invisible water vapor is a sufficient ballast. As it turns out, electricity is very orderly, and more powerful than thermal forces. If you want to see more, look up "Matt Finn: Electrical Dust Devils". It provides the above explanation with more detail and examples.

25:23 the vortex starts to "laminar"-ize. (I'm not sure if it is related to laminar flow in any way) 25:28 the inner zone can be seen 25:31 clearly distinguishable 25:33 disturbance, "laminar"-ization destabalizes briefly 25:38 from here on, pure sci-fi: connection symbol, background element/ lighting, AI consciousness, whatever you can think up. Amazing effect.
Went to a museum in Florida as almost 20 years ago and told myself when I was rich I'd have one of these in my house. This is the closest I've come to that, so thanks for helping me become a rich dude.
I think maybe its a slight oversimplification to say that a ball or whatever trapped in an air stream is there because of the low pressure created by the moving air. Whenever the ball deviates from the center of the stream, the stream gets preferentially attached to the side closest the the center of the stream and ejected from the opposite side. The net effect is the momentum change of the ejected air (which is always in the direction of the deviation) gets transferred to the ball, pushing it back towards the center. So it isn't the overall low pressure of the stream, but the very local pressure differential caused by the attaching and detaching air stream that keeps the ball centered. Maybe this is being pedantic. I don't know. I'm still putting it here. It would be interesting to see a smoke trail in the center of the stream and slow motion of how it moves.
Very interesting. I’d like to know a little bit more about the dynamics and what adding an afterburner could do to make a smokeless fire pit.
