As a former waterjet operator, these videos are super interesting and also explain a lot of the phenomenon that I noticed while I was working. You can definitely notice a similar effect with production 60k PSI machines(50 horsepower) while cutting granite surfaces. Most people don't notice it because we have bright lighting in the workshop, but at night with the lights off it was like a 1/4" ball of lightning. fascinating .
Most plasmas are influenced by magnetic fields. You might consider placing a rare earth magnet on the outside of the glass to see if you can cause distortion. Meller Optics sells sapphire windows. Elementsix sells small squares of single crystal, CVD diamond with the lowest price pieces (3mm x 3 mm) @ $125 each. This might then be re-purposed for another video where you use an UHV system to disassociate acetylene to thicken the diamond chip...and retire.

Is this similar to the "barometer light" produced by mercury on glass?
Cody'sLab Hi, Cody.
I bet it is! So, who's going to try the one-micron MERCURY JET version? :) Or see if the water-glow disappears if immersed in vapor from boiling mercury. Probably a contiguous jet wouldn't work, would short out different regions. But a string of droplets might make flashes.
Offtopic: see vid "cloud chamber in five minutes." I just noticed it. Impressive simple. A local guy was making these with 2-layer peltier coolers (no dry ice.) But way simpler: FREEZE SPRAY!
I hadn't heard of barometer light. Fascinating! Since you are the master of mercury, this has to be on your topics list, no? :)
I can't seem to find a video on this phenomenon. But I have a feeling one might pop up in my video feed in the near future. (Looking at you, Cody)
Applied Science, I smell a collaboration video!
Might be interesting to put a needle probe as close as you can to the "bend" in the water to see if you can measure the voltage
mikeselectricstuff
Droplets of water are charged positively on the outside. See uwashingtons Gerald Pollack The smaller the droplet the more positive it is. Your water jet is making nanoparticles of water and they are all positively charged on the outside. And that generates a electric current as they leave the vicinity. The reason it dims as you make the Surface irregular, is you're getting less nanoparticles. This is how lightning generates its plasma. Just waiting for a high-voltage and someplace to break down.
Sorry to say it but that sounds like pseudoscience. i just looked up that Dr Gerald Pollack and is very obvious is a typical scammer. Lighting generates its plasma due joule heating and ionization due free electrons.
Yes, but does peeing on an electric fence produce plasma?
@Teresa Shinkansen That might be pseudosci, but you've made a major error: Dr. Pollack is a (quite heavily funded) PhD researcher in bioeng. dept. here at the UW Seattle, with a long string of peer-review papers and a couple of textbooks (decades before his breakthrough on water microstructure.) The 2009 Annual Faculty Lecture was Pollack, see uwtv.org/series/faculty-lectures/watch/XVBEwn6iWOo/ Skeptics: never judge by appearances, always do proper homework, or you may yourself be the target of ridicule.
@wbeaty Can you please show me some of his peer reviewed research about his water structure theory? many of his published papers are published by Ebner & Sons publishers which is a publishing company dedicated to only his books and founded by himself!
There are so many websites that use his "research" to sell products. Look up pyramid energy or radionics or quantum-magnetic biology energy, ozone therapy etc; it is exactly the same structure of website and technical gibberish. Pure gimmicks and scams.
I don't care if i get ridiculed by people like you for being wrong, i learn and that's it. however if im right i don't get scammed and i help people realize the scams.
I got this from one of those websites that sells dodgy "water structuring units" with secret tech for patent reasons.

Were are the experiments that prove his "theory" which is more of an hypothesis?
That video isn't enough, all what it seems is to be a distorted notion of surface tension and trickery surrounded on commonly know phenomena and demonstrations of physics to introduce some truth to his hypothesis, im sure its just osmotic pressure difference between the gels and the micro spheres on its medium, why he never mentioned that as possible cause? the nafion is a polymer with ionic properties, highly protonated due its groups terminated with sulfonate so is obvious the Ph sensitive dye was going to change color close to it! Then he talks about imaging on a IR microscope the interaction layer of water on a surface of nafion were he claims he sees a significant temperature gradient, that means he was using thermal imaging, to my knowledge long wave IR microscopes don't exist yet.
Try putting a fluorescent dye in the water. Shouldn't mess with the conductivity too much, but should glow a lot more
why would it glow more? the hypothesis is that the air is what creates the plasma light, not the water
The plasma would create UV light which would make the dye in the water glow.
Yes, glowing of fractured wintergreen Lifesavers is actually high-volt corona glow nitrogen/oxygen. Apparently all sugar candies do this. But wintergreen oil flares brilliant blue when hit by UV.
I bet if you tried gasoline it would glow.
Please try introducing a charge (- or + ) to the nozzle to see if potential diffrence makes any diffrence . Thank you
_Thank you for the 60fps!_
All the non-jet shots were so buttery! It's easier on the eyes and feels like I'm really there, in the shop, with you.
You know it gets serious when a ~2" steel rod starts ballooning from pressure. But fun aside, I highly respect you for your genius and perfectly executed projects. Please keep it up and stay safe! Greetings from Germany, raBit.
Perfluorocarbon would be interesting because it is a polar molecule and it has a high dielectric strength. 3M sells it under the name "Novec". Maybe the plasma formation will increase because of its high insulation capability. You could also try to use the FC40 Fluorinert from one of your videos.
Thats what i said! Fluorinert!
That would make a nice fuorinert fog in his workshop...... not sure if that is a good idea.
Not sure how easy it will be, but an enclosure that contains alle the mist from the high pressure atomisation action will be a good idea to complete before proceeding with other fluids.
Spam Spammesen FC-40 is non toxic and very inert. You can look it up in the safety datasheet from 3M. It can cary so much oxygen that a rat can breathe in the liquid. In the datasheet it says that it is not harmful if you breathe it in.
Hahah, who would've thought the solid-looking bar would be the part that stops working first!? Cool video, as always!
Your smile is contagious; I was already smiling after reading the video title but that was very nice.
These energy focusing phenomena are the most interesting and surprising in all of physics. Barometer light, pyroelectric crystal nuclear fusion, scotch tape x-rays, sonoluminescence......amazing.
The Waterjet channel guys should love this...
First of all Great work and contribution Bro!!! For Oil, use a Metal plate in place of the glass in the present experiment sure you will see the similar triboelectric luminescence. This experiment is a corollary for another phenomenology associated with Water and that is the explosive force(Peter granaue et. al 1991) resulting when water droplets/mist is exposed to electric spark. I always wanted to prove the Triboelectric basis for this effect from a long time and you have just done that!!! Thank you very much!
Cavitation. Mantis shrimps' kill strike have the same effect, when the speed causes water cavitation.
Thanks for waiting for April 2nd to upload. Everyone else has been uploading videos I don't know weather I can trust or not. I knew I could always trust Applied Science!
Brendan Stanford The video was uploaded april 1st. It clearly says so right below the video.
lhl2500. Not on the east coast, or anywhere east of here.
Brendan Stanford he lives on the west coast though
Sam Koch. I'm not sure how the laws of time zones apply, can you enlighten? I watched this video 2 minutes after it was published and it was April 2nd my time. I guess it doesn't really matter cause the basis of my comment was supposed to be humorous
Brendan Stanford you said in your original comment "Thanks for waiting for April 2nd to upload." But he lives on the west coast so he didn't wait, he uploaded it on April 1st.
i love this channel. such quality content. thanx for sharing!
Wow the last year i found that paper, and always wanted to do it, but you did it first! Thanks for your video!
When the plasma gets dimmer, does it go back to being brighter if you move it onto a spot that hasn't been abraded?
I'm wondering: as the water creates a pit in the surface, wouldn't the path of the water change from a 90 degree turn to something approaching a 180 degree turn? If the change in the water's path resulted in a shorter distance between the charges, would that result in the arcs becoming smaller and dimmer?
I was just looking for this! Yes, it seems unlikely that charge depletion would happen at such a large timescale.
I was thinking the same thing. Maybe he could use a hard, non-conductive material like granite and film it from the other side. The plasma should still be visible though not as spectacularly.
@@LandoCalrissiano The hardest component in granite is just quartz.
Good comment. I was just about suggest that the abrasion could be the cause,. The 180° turn would bury the charged region with little to no air exposure.
It's insane how many people I'm subscribed to are in the comments section. Love your work Ben!
An April fools winner! Something that sounds for all the world like an obvious April fools story yet is completely true. Well done, Sir!
Very interesting video as always. It would be so nice if you could share with us your background and what inspires you to come up with these videos. What fascinates me is that you always tackle obscure scientific phenomena, unlike the typical 'lemon battery style' projects found on TH-cam. Great work.
Ice:- anything clear that can stand up to the jet. Probably not possible to get *ice* cold enough and hard enough (perhaps an unusual phase of water) then test if it produces the plasma effect, thereby proving or disproving the triboelectric theory. Awesome experiment by the way. Thanks for sharing.
Ben! You are real scientist! Молодец!
Ferrofluid would be a interesting test to see if the magnetic fields could cause plasma to form
Ferrofluid is an oil though, and it stains everything. That would be a mess!
And is not inherently magnetized - just ferromagnetic.
He could do some thing with the atomizing effect like coat something in a super thin layer of oil, or try to use the atomized oil as a fuel source to burn for something. I also wonder if this effect happens on non clear items like metal or would that short out, and how would you be able to see it if you were to try something like that.
Are the particles in ferrofluid small enough to fit through the orifice though?
The plasma from the water jet could be manipulated with magnetic fields in the vicinity of the plasma - move it around, concentrate it, etc - like thin film growing plasma manipulation.
Might the dimming effect be caused by the surface of the material losing its flatness, changing the way the water flows? Getting high speed footage of the phenomenon might shed some light on what's happening.
For another fluid to try, what about some other polar substances, like alcohols? Could also be interesting testing water of varying temperatures. Who knows, maybe the increased energy available to a stream of very hot water produces a brighter plasma?
This is a pretty tall order, but I'd love to know what the voltage across the plasma is. Maybe a bit of acrylic with a couple of pockets machined to hold probes could give us a rough idea?
Output Coupler
Heating and cooling the water would change its viscosity too. I wonder if near-freezing water would glow brighter.
I had a similar intuition about the flatness. I suspect the water begins to get trapped and reflect differently in tiny pockets as the material begins to erode and that interferes with the path the water takes
Really cool video. You could try different solvents with different polarities . It would be interresting to see if there is a trent in the plasma intensity. I guess highly flamable solvents are to dangerous because of the misting.
Always a good day to see a notification from this channel.
BTW, the main reason I subscribed to this channel is the way you say bye at the end.
Cool setup!
A simple solution to the oil mist problem is FIRE! FIRE fixes everything!
LOL
750 watt atomizer, plus lighter.
Maybe check out big Clive's kerosene atomizer first.
When in doubt; C4.
They even use fire to fix fire. The fire department will do controlled burns around brush fires and forest fires to pre-emptively destroy areas around the fire to prevent it from spreading. So yeah, fire fixes everything. Even fire.
@@anonymic79 Punches a hole AND burns.
Gerald Pollack's work on the 4th phase of water is - in my opinion - relevant to this observation.
There is actually a structuring of water adjacent to hydrophilic surfaces/particles that is negatively charged.
The ability to structure and de-structure (phase change) operates our cell biology - and of course in the natural world.
It also offers energy for the functions previously assigned to pumps or any number of extraneous supports.
Another example that we live in a Electric Universe. Great video, thanks!
Propylene Glycol sounds like an interesting option.
I looks Just the same as sonoluminecense , or impeller cavitation .
This is my FAVORITE *NERDOUT* topic .
Well done !
Greets from the Netherlands
Johny geerts
I worked with water jet cutting on many types of materials, using 50,000 PSI, Australian garnet sand and 40 tho nozzle, when cutting Titanium I got a powerful fire like effect (blue to purple) going back up the beam of water/sand. It seems that the Ti is so hard that the Garnet is decomposing to an atomic level, and creates a kind of minute plasma effect inside the stream that erodes the Ti away. The finished surface of the Ti was quite different to say Core 10 steel, which is one of the hardest steels I cut. I never saw that effect on any other material like, woods, plastics, steels, aluminum, rock, granite, glass including Armour plate, Stainless steels, and even the broken pieces of tungsten carbide, that we cut into tools for use on model lathes.
An interesting aside.
We also had laser cutters and one interesting thing about core 10, is that as you cut it on the laser it "sings" as it releases the internal stresses, some other materials groaned or whispered too. LOL It was really a pity as all the core 10 we cut was being turned in to rubbish truck containers.
I don't normally comment, I'm a Lurker, but I really Appreciate your videos. For your Next experiment, you should find a way to multiply yourself by 2 so you can produce twice the content. Thank you. The video is pretty awesome too ;)
You could try hydrogen peroxide which is has a greater dipole moment than water. Also, you may shoot this in slow-motion to better understand this discharge phenomenon. I think that surface is etching away upon contact with water and forming a discontinuous section section like a crater, which is avoiding those sparks by increasing the gap between the glass surface and the air molecules(also, the charged material may be getting etched away, rather than getting accumulated so this explanation may be more apt). You may try harder materials like Ruby or Sapphire which should last longer.
this is a very interesting find, perhaps it will lead to a great discovery someday, good luck, and stay curious.
If it isn't an april fools joke, I'd recommend adding Fluorescein and reducing the pressure. If the water jet doesn't cut the material you could sustain and control tests, or try different impact angles. The fluorescent dye (or a phosphor instead) might make the charge separation visible without the pressure required to create plasma. Maybe this wont work for the same reason the water needs to be pure, because it would become slightly conductive.
Sir, you have earned my subscription because you present me with strange things I've never even thought of looking into before.
Thank you for expanding my horizon.
Would love to see a liquid metal stream, maybe mercury or some galium-based alloy. It would be interesting to see how the metal handled the increased pressure from the force of it being pushed through the orifice and it slamming against a backstop of some kind. I imagine you'd need a different orifice, given the viscosity of a liquid metal.
Thanks for these wonderful videos! I learn something new from almost each video you post!
You should try some alcohol, spirits and maybe even some completely conductive water just to test your theory
An interesting point to this if I may add. I'm almost positive this is due to the crystalline form of the glass. Check out the work from Dr Dan burisch on his work on crystals. He's able to propagate a plasma portal which also propagates RNA out of the portal plasma ball. This is a strict feature of a crystalline form and he gets this to propagate under a small voltage applied to a crystal. Not to mention compressing any Crystal for the most part will create a voltage
That is a really cool effect that you demonstrated there! I can think of lots of questions! Did you try using some ionic liquids (i dont know if there are any with a lower viscosity) or other liquids from polarized molecules? You could even try a gas!
How is the angle of impact relevant? Could you focus a microscope objective on it to get a resolved image? Does the effect change in a magnetic field?
Petrol contains additives that increase their conductivity exactly for this reason. When you fill huge tanks through plastic pipes, they could generate and accumulate electric charge, until it arcs, which would lead to disaster.
As always quality content on your channel ;) You can make highpressure homogenizer out of your setup
Excellent Vid.
Thanks
I have noticed this while using a gas powered pressure washer with DI water. The pressure was much lower ~4000psi but much more flow ~5gpm. While spraying non conductive parts in near darkness a very bright plasma glow is observed
That's pretty neat! I wonder how a suspension of solid particles would behave in this setup, if made in a shear thinning liquid like xanthan gum or something similar.
Does this effect have anything to do with sonoluminescence? Does it have anything to do with triboluminescence?
I said that before and I'll say it again : this is by far the most interesting channel on TH-cam for me. And Ben is the coolest dude, wish i knew him in person.
Does this explain the lightning made by the mantis shrimp when its throw it's jab in the water, it's not merely due to cavitation? 9:08 What about some 99% alcohol or other kind of volatile and different molecular density liquid as acetone?
That would be cavitation - the collapse of a vacuum bubble. It does actually create plasma, but it's an entirely different phenomenon.
thunderfoot has a video of water filled tube shaken to create cavitating vaccum bubbles,They didn't glow
+Suraj Grewal
that cavitation just wasn't fast enough
en.wikipedia.org/wiki/Sonoluminescence
We know it can't be because the effect described in the video doesn't work if there's salts in the water, and the mantis shrimp is a saltwater shrimp.
+Suraj Grewal yeah but the video he did had the water under a vacuum, so it required less energy to cavitate
A close up with a slow-mo cam would be very cool to see.
This is amazing, thank you sir.
silicon oil is an insulator and available in pretty low viscosities. I've seen it spark in the reservoir of a hydraulic system, keeps a charge for a long time. might be interesting. ps:
You can create a plasma in water by focusing high-frequency sound waves in the middle of a flask, and you can sustain the effect.
I was able to get this effect at work by accident. We were pressure washing the inside of a very large DI water tank that was having issues with bio buildup. The inside of the tank was coated with some sort of epoxy. We were running a 3000 psi pressure washer running at 3.5gpm. we were also running DI water through the pressure washer. We had previously rinsed the tank with a bleach solution to kill off anything and were rinsing with DI. Being a tank it was naturally dark and we were able to see this effect. Took a video of it, will see if I can dig it up.
If the water rapidly changing direction plays a big role, it'd be interesting to shoot some non-flat glass. Seems like a concave shape would force the water to change directuon even more; I wonder what would happen if the water was shot straight into a test tube. Or maybe the convex shape of the outside of a test tube would allow the water to separate more quickly or with less turbulence, potentially having an effect on how the plasma is generated.
Dry steam about 4-5 bar pressure can generate huge e.discharges if it blowing to massive isolated metal thing. I came across this phenomenon when I put a large wrench in a stream of steam. Steam exited through the tube to connect the pressure gauge. The discharges reached 50-70 mm.
Sputter a conductive surface on the back side of the target substrate, keeping it translucent enough to see the discharge. Apply high voltage dc between the nozzle and the metal sputtered target glass. Also, try attaching a capacitor between the two and see if it charges up.
Ethanol or ammonia seems worth a try, although the resulting cloud of flammable and toxic vapour would require care. Have you tried an argon atmosphere? A low pressure environment would be interesting too, but almost impossible to maintain , except perhaps using a low vapour pressure ionic liquid? ITO glass? Some enamel wire probes would let you measure the electric fields with a suitable electrometer, it may scale with pressure/velocity so charge separation may be detectable with streams below the destruction threshold of the target. Maybe you can light a neon bulb or LED with the tribocurrent well before air ionisation? Although looking at the brightness of the discharge the current looks very low, the process is clearly extremely inefficient. Diamond or silicon carbide would be an interesting, tough and conductive target.
I am guessing you will replace the piston with a solid rod to achieve higher pressures? How does the seal on that thing work?
If it makes ignite the alcohol, it could be used as a "non electronic" ignition system (for rockets)???
I wonder if you can alter the effect with directional sound waves? Maybe create a cushion for the water. Might, small m, protect the lense a tad longer.
Heavy water might be too expensive to send through but would be interesting to see if it shows the same effects. Should be because the charges are the same. Maybe you would also need a more precise detection method to evaluate subtle changes.
Liquid ammonia?
Also you should make an enclosure for the nozzle+material. That way any vapors and droplets should be contained. Maybe a fume hood-like setup where the enclosure is actively vented to the outside.
A couple other interesting experiments:
If you pretreat the glass under UV-Ozone plasma the surface will become hydrophilic by adding hydroxyl groups to the glass surface. The charge separation and friction might be enhanced ... or suppressed . Either way, you should see a huge difference.
If you put a magnet behind the glass then you might see a moving pattern. Increasing the diameter might help you see this. The plasma will move under a magnetic field by simple Lorentz force.
This is so cool!
I always look forward to your videos, so much to ponder. I wonder if there in an interesting industrial application to this. Another way to generate electricity?
Water is one of the best insulators, so its not surprising it works.
might be hard to pull it thorugh, but liquid metal and ionic liquids would be cool to see
Would you get better charge separation by using distilled or deionized water? Also interesting would be an alcohol or chlorinated solvent.
Nice work.
You could try it with chloroform, but make sure it's very clean and dry. It's a polar insulator. I see some are suggesting ethanol, but given there's plasma and air, that would ignite the mist and possibly even cause an explosion. Ethanol would be ok in a closed environment purged with nitrogen.
If you're going to make an enclosure, I recommend glass with plastic lamination (either between two glass sheets or outside) because chloroform melts a great deal of polymers.
I wonder about the solid substrate used -- Have you tried any conductive ones? Something like indium tin oxide is still transparent, but also conductive. As for other liquids to try, perhaps acetone, ammonium (though that might be somewhat conductive), or acetonitrile. I would highly suggest putting the cover on the bin you were using in the video for any of those.
Nice yellow mug!
I would recommend trying other polar solvents like glacial acetic acid or ammonia. (You would need to build a better enclosure though)
Fascinating! Thanks.
I would try mixing some glycerin in with the water to improve its dielectric properties.
That may improve the charge separation and result in a stronger arc.
You mention the wattage at the target site and I wonder if it's possible to recover (or at least play with, via the o-scope or into a light bank) some of that energy by using a target material with a strong piezoelectric effect? It might show something that characterizes the target's deformation or be a weird "turn water into power without turbines" kind of silliness...
For the pressure vessel..... it shouldn't be that hard to make your own heavy walled vessel. And then build it like an intensifier. Haskel pumps could be used as inspiration. Drwaings of these are available online, Use them for inspiration, and you should be able to get good working high pressure pumps.
Or..... get a genuine Haskel pump made for these pressures.
Or do as some waterjet systems, make a high pressure intensifier, with a relatively low ratio and a normal 700 Bar pump as input.
There are many ways to accomplish this in a one-off DIY setting like you have.
Keep up the good work!
Nice vacuum variable capacitor in the background there!
What are you going to use it for?
Facinatng. If you do it with alcahol does it ignite? if you do it in a deuterium atmosphere can you detect fusion? saphire might hold up better than glass (or diamond of course, if you happen to have one lieing about :P) the reduction in glow after a few seconds might be due to the glass getting damaged and water no longer striking it at a rightangle. if you tilt the glass do you get the same effect?
Wonder what would happen if you put a conductor behind the glass on the rear side. Would it produce a voltage? And second, what happens if you apply voltage to said conductor?
Great video. Thanks! =)
Reminds me of sonoluminescense.
I suggest checking out the work done by Dr Gerald Pollack on the properties of water within 50 microns-ish of a hydrophilic surfaces. It might explain why the different materials were able to create the effect. If it is the case, you might be able to enhance the effect or reduce the pressure required by shining some specific wavelengths of light (that are absorbed readily by water) at the water at the impact site, such at 950nm (some security lighting emit this) or 3000nm.
Would be interesting to see this in a case where the material is not removed from the surface because I recall the fracture of glass and other such materials generating a visible arc at the fracture point so I'm not sure this is happening because of the water so much as the material being chipped away in a controlled manner that focuses the arc at a position.
Peter Plichta, a German chemist, described this plasma-effect occurs by just stearing higher aliphatic chain length silane.
Absolutely fascinating to see this effect in action, I remember reading about it a couple weeks ago on phys.org. Would it be possible to create a setup to collect the excess charge with an electrode or something? What happens if you try to shoot the water jet on a conductive material?
Great video. I would be interest if you tried to find the lowest pressure that still produces the effect. Also ethanol would probably work as a polar molecule is clean itself up by evaporating. Or catching fire, now that I think of the plasma. So ethanol is a prepared setup.
@applied science I think that the plasma is dimming down (not because of the charge being depleted) but because the water is damaging the surface and changing the way the water is deflected away. If the surface is smooth and clean then the water will smoothly deflect at 90 degrees, however if the water starts to pit or drill into the material then the deflection will change. Does this happen on any material that doesn't get damaged? How about does this happen less on materials that are damaged less and more on materials that have more damage or damaged more quickly? I think I saw that when you moved the stream back over the already damaged that the plasma was much brighter and intense than before, leading me to think that the deflection shape is having something to do with it. Great video, never seen this before today. Exciting stuff.
If you used alcohol, would it end up more like a flame shooter?
You should try other thin liquids like vinegar as well. Both usually have a lot of water, but it would still align with the saline test. Oh.. also try saline for contact lens wearers - different kind of salt.
Hi, congrats for your channel. Did you have any tutorial or video about the hish pressure pump that can see in this video? |Im looking dor make a water jet pump but with a reasonable pressure at low cost. any suggestion? target is goes to some thousands psi.
Thanks
BR
Justo
Maybe you can apply a high voltage charge to the orifice somehow and see if the effect is multiplied or if reversed, negated. Very interesting!
I really want to believe that this isn't an April fool's prank, but my brain just says no. On the other hand, it's one of the more convincing April fool's pranks I've seen if that is indeed what I'm seeing.
You can check sapphire watch crystal replacement as substrate.
Try a water-sugar solution. Sugar shows in the solidstate triboluminescence (blue glowing). I am curious if there would be an effect to the glowing (If there is one it would be interesting to add also wintergreen oil, which is easily avaible in america as far as i know).
Replace the microscope slide with sapphire. If the orifice holds up, the target should hold up as well. You could borrow that ruby rod from the DIY laser, right?
I have 2 cool ideas for this setup: a magnetohydrodynamic generator needs an ionised liquid at high velocity to produce some reasonable power.
And what about heating up the stream? Some supersonic air blasters use a regular air compressor and just heat up the flowing air to make it expand. By turning this water jet into wet steam you will definitely get more energy into it. And that just has to influence the experiment in some way. And steam is a compressible gas. That compressibility gives it some springiness on impact. And I suspect supersonic dry steam will temporarily turn into water on impact because of the impact pressure. On dangers of this experiment: only the water that is inside the pipe will be hot, you won't have a full container with pressurised steam.
How about using saphire glass as substrate as well? They come quite cheap on eBay for good sizes, and should hold up much better.
Wery usefull for many things, so a good ting to have lying around when you are doing experiments like you do!
Thanks for showing great content! I really enjoy your channel!
Did you test at what pressure the effect starts to happen? From that you should be able to figure out based on the volume the energy density of that area and look up other plasma reactions to compare their energy densities.
The other point of interest would be does it get brighter if you increase the pressure?
Would be interesting to weigh the objects before and after. I wonder if material is being vapourised?
Interesting. Heavy water and ethylene glycol would be 2 things it like to see put through this setup.
@Applied science It's cavitation. Measure with DOSIMETER!
Fascinating video! :-) Would be at all possible to recreate this same experiment with a flammable fluid such as alcohol or gasoline?
I would be curious to see if the plasma would ignite the flammable fluid(s). Testing it outdoors of course. :-)
Thumbs up video!👍
