Fill the vacuum nozzle with coffee-stirrer straws, and possibly isolate it from vibrations with a separate chamber in order to get a laminar flow of air. It should give you MUCH better results. (I built a laminar water fountain with similar techniques and its just beautiful)
Cool! In the laser hobbyist community we call that the 'liquid sky effect', when you see all the eddies and currents and swirls of the fog in the laser line.
I remember smoking on my best friends floor and if it was late enough in the afternoon, the blinds would only let sunlight through one slit in them and blowing smoke towards it entertained us nonstop haha. cheers fellow Michigander.
This is just a theory, BUT I think you can map out those vortex at 2:20-2:30 minutes in the video, in 3D... You very slowly waved the laser up and down and so fourth, I was proposing you do the SAME thing except with a camera with a slow shutter speed so you capture a 3D IMAGE of those vortex..... it's just a theory and might require some editing after every shot, but you could map out those vortex literally!
You should try your hand at some schlieren photography. That, plus a high speed camera would definitely show you the air currents behind that screwdriver. You just need a long hallway, some parabolic mirrors, a candle, and other stuff.
Did you try this experiment with a longer handled screwdriver? Also @ 5:20 do you see how the different pressures are interacting towards the output port? So cool, like the low pressure air is being sucked into the chamber!
It’s somewhat like an mri of the air currents, providing a 3D image of the air body through 2D slices. You could use a camera and software the create a 3D render of the 2D slices, the reverse of a slicer for 3D printing.
@NightHawkInLight Record a 3D fluid dynamics environment by creating a large array of laser slices that are timed to pulse in very small time intervals effectively scanning the environment. Recording this with a high speed camera and good resolution could allow that data to create a very precise model of the fluid dynamics environment.
I think the problem is that because of the high speed, the flow of air is turbulent, so you can't see nice patterns. You could try packing the blower's nozzle with drinking straws or coffee stirrers to produce a laminar flow that might be more interesting.
A few more lasers could help. Using different colors for X, Y, and Z and centered each plane on the point of interest might help show the high and low. The more concentrated the particles (low pressure) the more the colors should mix volumetrically -- a region of higher refraction?
Also simulating this phenomena at a much slower speed could reveal higher detail. Maybe you could prop the screw driver at the tip and use a very low blow speed. For comparing multiple stages you'd need another set of width and length axis lasers, and probably a second vertical laser to remedy the shadow of the first vertical laser.
Great video, yet you can make a better set-up using Fourier optics laws. Type "Schlieren photography" in google, it's a visual process that is used to photograph the flow of fluids of varying density.
PUT ON SOME IR PROTECTION. Those cheap green lasers emit a ton of IR that'll easily damage your eyes. You even mentioned they do this so why not follow your own advice and get you some? Sure beats squinting the rest of your life.
+NightHawkInLight dude I remember when you had about 1,000 subscribers for more than a year. congrats dude you must be happy with how your channel turned out
What if you put your entire system for floating the screwdriver in a smaller space? So that you can fill the enclosed space with thicker fog and then your cross section might be a little more visible?
Pretty gutsy move to put that pick in a high pressure stream of air. It looked like it could just as easily flown sideways into your neck. Safety Sally out.
Were no eye safe lasers (class 1, I believe) available with the optics you wanted? Or is there a reason that they would not have worked? 50 mW seems like quite a bit, and as you said, if would have easily damaged your eyes if you messed up or were unlucky.
I wore them most of the time but took them off when I had the laser mounted in a secure position and felt safe to do so. It was necessary to have them off at times because I could not tell what I was filming while I had them on because they make the laser invisible.
2:50 "Eddy current"? Are you sure that it is the right word? As far as i am aware eddy currents are electrical currents that form with the presens of a magnetic flield...
@@rstriker21: indeed. Both points of view are correct: "The term eddy current comes from analogous currents seen in water in fluid dynamics, causing localised areas of turbulence known as eddies giving rise to persistent vortices. Somewhat analogously, eddy currents can take time to build up and can persist for very short times in conductors due to their inductance." (Wikipedia)
Taking laser and fog machines out of the concert scene! if its a low pressure behind the screw driver why would there be more particles? a low pressure should create a void, and our eyes aren't so good at picking a void out in a lit situation. or so my brain tells me with no more fact checking than my gut. and as mentioned later in comments by someone laminar flow is helpful for the Coanada effect.

*badum tss*
you didn't even spell enlightening right
+Yung Mulah Gaming really
+Yung Mulah Gaming Well at least you know the word
This brightened my day.
How beautiful!
Cool experiment!
Love your videos NightHawk!

Very cool demo!
That wide Beam Laser is pretty sweet, thanks for another cool video :)
This was one of the coolest things I've seen in a while, thank you!
PLEASE MORE LASER AND OPTICAL CONTENT!!!!!
Us laser enthusiasts are starving for good content regarding lasers, optics, and the evolving technology.
Wow. That is psychedelic. Awesome video!
This looks pretty cool.
Saw your video on tv! So cool!
Super interesting idea man! 👍
Honestly such a cool video!
Great Project, thanks for sharing
Man i love your videos
Keep up the good work :) you have a really interesting channel
Very neat. Use you laser at your next camp fire. Also a good show.
Last time i was this early Harambe was having a great time alive...
Please stop with the "Last time i was this early..." comments.
#dicksout
Ramen-Powered Shit Factory but harambe...
Ivan Petrus I know it hurts but you gotta let him go or he'll never rest in peace
Ramen-Powered Shit Factory His corpse isn't resting. It's rotting. Nothing we do can change that.
This would make an interest in effect on a ceiling for parties.

Oh! That is that shirt from "Bleach shirts" episode! Awesome pattern !
Hot damn that looks amazing! Really clever too.
That is fucking amazing to look at. Gives you a new perspective of what is moving in the air.
More experiments!
wow.. looks so surreal
Excellent!!
That is really cool to watch! It would be awesome to set something like that up in my room at night! hahaha! Love it!
nice work mate
Hey thanks for another great video! Love this.
awesome experiment
Amazing air currents when slow .. You may try various objects in a wind tunnel with fog and a laser cross section
Please purchase some laser safety glasses. I love your videos and don't want you to go blind.

you look a bit like shia labeouf
Mixed with Orlando Bloom and Liam Neeson.
Yeah he does. The first video I saw of his was the cigar box guitar video. I said something like "I didn't know Shia Labeouf made guitars"
glad someone else noticed too
I really want to know how old he is too.
Reminded me more of Fidel Castro with the longer beard.
Pretty neat 🤓
Wow, you are a super nerd! loved the video!
Mind. Blown.
You have resources and ingenuity. Make a Schlieren setup with that mirror you made with space blankets.
You could see the low pressure behind it in fleeting moments. Fun!

this would make a good light show for a band
this guy is a genius!
Yeah he is !
sorta maybe but coming up with all the setup and actual content is amazing, isnt it?
Try this technique with one of those bladeless fans from dyson!

Has a nice psychedelic effect. Imagine using this slow motion bits as a texture of some sorts

I want this as my desktop background 1:56
What does a spinning top do to the look of fog in an enclosed area? Like a beyblade or something
That would be pretty interesting
+NightHawkInLight sup
Make a laser grid and make a video of how it goes. My mind will be absolutely blown.
ITS MY FAVOURITE OF THIS YEAR ❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤

Caution: 3B laser class is not directly on the radio thenaked eye, in order to avoid the eyes hurt!
I like to avoid the eyes hurt
also is it indirectly on the radio?
Wow awesome!
I wonder if you could use this laser setup with a smoke ring blower to get an old school 1950's Ray gun effect
would give so much more depth with just two. Spaced parallel with different gaps or just make a cross section X. but very cool effect.
Amazing! !
dude I subscribed to you years ago and for some reason you're never in my feed. what did you do to piss off youtube
Can you spin the laser really fast so it would make a 3d view of the smoke?
Or you could just use a regular light, which will also create a 3d view of the smoke
You could spin the laser really fast if your goal was to blind everyone in the room :P
Or spin it slowly, letting our brains fill it in... and/or shoot with two cameras, to get stereoscopic 3D effects...
That's some trippy shit.
Next up an array of these wide angle beams set up in a way to achieve a cubic illumination of the smoke being observed, rather than a sheet.
did you ever mount the 10ft length of pipe fog horn to your truck?
Not yet.
+NightHawkInLight hi NightHawkInLight im your bigist fan!!
NightHawkInLight you should though
+NightHawkInLight dude I remember when you had about 1,000 subscribers for more than a year. congrats dude you must be happy with how your channel turned out
+TheMastergabe I've been here since 150 xD
You can also use a hot water humidifier and move the laser back and forth a whole bunch.
Awesome
I wonder if this is being used in analysis of fluid dynamics.
Dude, you're my hero!

I really wonder if you could win a vfx oscar for if you worked in film.

Waaaaaaaay cool effect! But I must say that was a terrible waste of perfectly fine cheeseballs! SAVE THE CHEESEBALLS! Lol.
Is this the use of the Tyndall effect?
Try and find a way to rapidly spin the laser pointer, it should give you a 3D cone effect.
I think it would be interesting to see a cross section of a vortex cannon ring
Who's here from 3B1B?
Strangely, I'm not! Though I do frequent that channel, so maybe I am via The Algorithm, even though not directly.
Brilliant
what if you use multiple lasers stacked on top of each other, then you can see the 3 dimensions imagery of the air movement instead of two dimensions
Dude use this in a cloud chamber to detect cosmic rays. Trust me you'll love it.
got so caught up with the safety precautions that you forgot to put on your laser safety protection tisk tisk
2:50 "Eddy current"? Are you sure that it is the right word? As far as i am aware eddy currents are electrical currents that form with the presens of a magnetic flield...
Same lol.
I was thing like eddies in a river

Huh. You know without the beard NightHawk looks more human than his normal god-like self...
Can we use the flashlight, instead of laser?
Is the smoke laminar or turbulent to create those psy light ? Il trying to do that in a "wind box". Same machine for smog but i don t use bottle
Everything in this video is turbulent.
Spin the screw driver? the angular momentum should stabilize it longer. I think.
when it moves through the air, it reminds me of a CT scan
lasers are so cool...eue
what is the song called? Cool project by the way :)
Taking laser and fog machines out of the concert scene!
if its a low pressure behind the screw driver why would there be more particles? a low pressure should create a void, and our eyes aren't so good at picking a void out in a lit situation. or so my brain tells me with no more fact checking than my gut. and as mentioned later in comments by someone laminar flow is helpful for the Coanada effect.
Heavy fog particles have more tendency to fall into a low pressure area than the air around them.
I guess if you made the screw driver spin for centrifugal force would hold it in place longer and better.
The label says: Caution: 3B laser class is not directly on the radio thenaked eye, in order to avoid the eyes hurt!
I was about to ask where you got that shirt then I realised you made it I'm such a twat 😂😂😂😂😂
Can I just use a laser leveler for this affect?
What if you bought 16 lasers :3 Then you put them in a 3D graph form?
Would it be possible for you to set up the laser to rotate showing a 3d volume of air?
That's a good idea
would love to see a vid of this with the laser spinning rapidly
