@@sauroman1 no you don't need a perfect vacuum or tungstan or beryllium.It even works with ac. It gets more efficient with dc and the tungstan plate but it works under very simple conditions.

Hi, in this interesting experiment, I think would be *exceptionally interesting* if you could make one of the vacuum chamber sides (i.e. right side) connected electrically to the ground pole of the Tesla Coil using an aluminum foil.... I think, while lowering the air pressure, some very interesting pattern should appear from the central pole of the coil and that "ground". Electricity should "diffuse" or spread over a wider area (or maybe VOLUME) and would be interesting how this diffused "plasma" reacts to an external (moving) magnet moved by hand... I think your videos are very educative and, like me as an Italian, very clear, while you speak in your typical clear and calm mode. THANKS!
This sounds like very interesting experiment to do especially the part with magnets since magnets and electricity make funny things when they mix and move.
Love your channel! Rain X is supposed to fiil in the porous surface on glass to make it have even less friction. You should do a video to see if your metal disc will spin longer on a rain x treated mirror.
I don't know how comfortable you are with high voltage in general, but there's a lot of fascinating experiments to be done with a vacuum chamber. About 5 years ago I did some tinkering with capacitor discharge in a vacuum, using 5kV 2 microfarad caps, but you'd be able to use a neon sign transformer to the same effect quite easily and definitely more safely.
You sir have the gift of narrating the superficial observation via “play by play” as if we are blind, but otherwise adding no valuable insight. “That’s so cool!” If you didn’t tell me “it’s spinning” I’m sure I wouldn’t know it by watching the video. “Whooo!”
Have you done experiment to see whether straight light beam is visible in vacuum chamber from a side. I’m curious. ? No particles to reflect light to my eyes in the chamber?Thank you for your mind blowing videos.
I read years ago that the thrust is caused by the local air being ionized by the high voltage and then it rushes away to equalize creating thrust. I made one using aluminum foil and an old tv set and paper clips. If you can get your hand close without getting shocked you can feel the air rushing away.
I'd say that electrons are pushing air around, if it was due to the heat then the wires would be either red hot or melt (and metals are good heat conductors so it would be easy for heat to spread)
SO you are correct- it is the expansion of heated atmospheric gas that causes the spin. This effect is related to ionic wind but only due to the repulsion of charges. When the charges neutralize, the recombination of the electrons is what causes the glow. As the air pressure drops, the sparks increase in length because the "mean free path" is increasing. This is the distance that an ionized particle will move before colliding with another particle. There are literally less molecules to collide with as the pressure drops, and so the sparks become longer. But as the pressure drops below some threshold, there are less atoms to become charged and the glow changes to a much more localized effect. Air is a partial insulator with what is known as a dielectric breakdown or "puncture" voltage. When there is a much lower number of air molecules nearby, there is a greater chance that the charges will be more evenly shared- thus a soft glow instead of an aggressive spark. In very low pressure it is difficult if not impossible to have a lightning bolt or spark. You get instead a cloud of charged air molecules that has a soft "neon" sort of glow.
Dude, that diagram and explanation of the cascading effect of electrons is how I imagine photons, thus explaining how they [photons] act like a wave/particle.
Awesome vid & "breakdown" of the voltage (pun intended) 👍 What happens to the missing electron if it doesn't succeed in breaking another one free from its atom. 🤔
No. The spinning is not due to heat !!! It's caused by ion wind. When air an atom is ionized near a negatively charged electrode, it becomes a negative ion which is repelled by the negative charge and flies away from the electrode. Since electric field concentrates at pointy parts, the effect is an ion wind made of ionized air molecules flying away of each pointy end of the electrode in opposite directions thus creating torque and making it spin.
I have been researching this since I made this video and it is actually due to the Ponderomotive force. Not exactly an ion wind. This is a force in a non-linear oscillating electric field. I am editing my video to take cut out the part that I talk about heat, since I am now 99% sure this is not correct. It should
Ah, but you can do this same thing with a Van D'Graaff generator which is DC, direct voltage, not AC. Wimshurst machines do it too, which are also DC. redrok@redrok.com
Here is another view of it. Place diodes of sufficient rating to handle the high voltages so current flows only in one direction or another. a)When a tip is positive charged, electric field lines diverge from the tip electrons are striped from from neutral molecules. Now positively charge ions are pushed away from the tip along electric field lines, with those same positive ions also pushing against the positive charged tip. b)When a tip is negatively charged, electric field lines diverge from the tip. Electrons are either ejected and or charge neutrally charged gaseous molecules. Now negative charges are pushed away from the tip along electric field lines, with those same negative charges pushing against the negatively charged tip. Lesson learned is that thrust is generated when the tip is either negatively or positively charged from electrostatic pressure pushing on the ions and the direction of diverging field lines pushing ions away from the tip. The question is if the current is alternating, wouldn't the ions just reverse direction providing no net thrust. and given the fact that it does spin, does that really mean it is not due to electrostatic thrust, and must be caused by thermal expansion? No.... the ions are electrostaticly pushed in one direction away from the electrode. Since the ions are accelerated in mostly one direction and are slowed down through collisions with neutral molecules, and other ions with the same charge that have been slowed down, they tend to hang around a while little longer imparting more electrostatic force on the tip, as demonstrated with not as strong of a vacuum pressure. Then for a period of time the voltage drops below that which can ionize the air and the ions and tip travel further distance away from each other. In time the voltages reverses and eventually reaches a voltage that can ionize again with nothing but neutral gas molecules near by to be charged and repulsed. Distant ions of opposing charge are not as effected (do not change their momentum as much) because of their distance from the tip. The result is net thrust in one direction even with alternating currents. What is the source of thermal energy in a plasma discharge and does it have a direction? I am venturing a little beyond my sure understanding, but in a lightning strike, some thermal energy is caused by the acceleration of ions in a particular direction, they bump into neutral atoms exchanging momentum in the random collisions in front of them that in turn slowing down the ions down. Furthermore, as with all conductors, electric current causes a magnetic field. In a lighting strike, billions of amps are discharged in a fraction of second. Some energy from the discharge gets stored in a magnetic field and is released when the current stops. The ions' (unbalanced electrons) will be magnetically have fields aligned at a right angle to the direction of current flow. Those ions most strongly repel other ions in the plane at 90 degrees to the current flow. The magnetically constrained ions will jump in temperature with a magnetocaloric effect over neutral molecules. The newly aligned magnetocaloricly heated ions have a lot momentum to impart to neutral molecules and ions in the plane of their magnetic field 90 degrees from the flow of current.
Well... yeah, because actually what I described works only with DC. However the Ponderomotive force is basically a more complicated form of the same. I mean one might think that with AC ionized air molecules would be just wiggled back and forth near the electrode due to the alternating polarity of the electric field, however its nonuniformity with distance results in a net push away from the electrode.
Years ago, I designed an avionics instrument that included a CRT display. The CRT needed 10KV on the second anode. I had to put a LOT of work into figuring out how to handle the high voltage insulation so that it could make it to 50,000 foot altitude without arcing over and destroying all the electronics in the instrument.

Hey i have a question from my childhood When we see a wheel of a car or anything else like that spinning fast First we see that it's spinning forward then it looks like it spins backward what is the reason
It all has to do with the frame rate of our eyes: our eyes take several "photos" per second, which when put together in sequence by our brain, give us the effect of motion, very much like a conventional video camera. Now, imagine if you observe a single point on a spinning wheel. If it spins at such a speed, that between 2 consecutive "photos" your eyes take, it can make a little more than 1 revolution and appear a little further than the previous position, then you get the impression that the wheel indeed spins forward. But if the speed of revolution increases even further, so that the point we observe makes a little less than 2 revolutions in between 2 consecutive "photos" of our eyes take, then in the 2nd "photo" the point would appear a little behind the position in the 1st. This would give us the impression that the wheel spins backwards. And of course, if the wheel spins at the exact frame rate of our eyes (the point we observe makes exactly 1 revolution in between 2 consecutive "photos"), then it would appear stationary. I hope it makes sense to you. Visually it would be much easier to explain.
@@andreasgeorgilidakisawesome explanation! so if we know the exact frame rate of our personal eyeball, we could - in theory - determine the rpm of a speeding wheel based on how fast it appears to track in reverse??
@@HarlanHarvey76 that would be tricky, as we don't have all the information... We don't know how many revolutions the wheel makes between 2 consecutive "eye frames". For example, in the 2nd frame the point on the wheel that we observe, could appear 1 inch behind the spot that the point appeared in the 1st frame (and in the 3rd frame, 1 inch behind the spot of the 2nd frame and so on), BUT... we cannot know how many revolutions occurred in between the "eye frames"! Was it a little less than 1, or 2, or 3, or more revolutions? The point on the wheel could appear to be on the same spot in all these occasions.
Question: Action Lab, if the higher the pressure means the faster the spin; what if you shoved that in a jet engine (no fire) instead of a wire; use a jet propeller & see how fast it can spin & how much thrust you can get off it... Might just be a replacement for jet fuel.... Not to mention the sparks could be used to provide the heat for the higher pressure
Grant Farrell FICTION?!?! O right those astronauts theyre all fake man, a yt video is the only evidence we have of SPACESUITS working... oh boy u got me there
That is a fancy plasma ball or cube lol. This is the reason I use a plasma ball for an exciter instead of a tesla coil it works almost the same and they are the work of Nicola Tesla. I loved your exeperiment it is very useful information for me. Thank you for sharing this video awesome.
James hope your well, I wondered if you might do a video on negative ions because when I put smoke/vape in a box it cleared the air completely so does this mean its a good idea to have a negative ion generator in the home? And pollution in the air if you had a metal plate that was just cold enough to produce water droplets would the pollution get trapped in the water I was thinking of building one out of Peltier's but I have no way of seeing if the pollution is in the water or not. Keep up the good work cracking channel you have developed.

What would happen if you had a pair of open scissors that had blades a lightyear long, tips a lightyear apart, handles below the fulcrum are the size of that of normal-sized scissors... and you closed them in a perfect vacuum with no atoms or photons to cause drag on the blades as they closed? I would imagine they would either have to break the speed of light to match the speed at which the handles meet or some unknown force would impose resistance on the blades to keep them from breaking that rule (and making the handles REALLY hard to close).
at 4:10 when its spinning i can see the light of the sparks draw a circle but its not an continuous line. It seems like several constant width lines with dark gaps between them. Is this caused by the frame rate of the camera and the coil's frequency? Is this visible at naked eye? If so, you could plug in a frequency generator to the tesla coil (if it can play music...) and see what visual effects it shows.
You have one large magnet and note the polarity so that you know which side is north. If you break it would the polarity flip on the new piece when you place them parallel or would they be the same? If they do then isn't "opposites attract" wrong. Maybe you could do a video explaining it. Thank you for the lesson.
1) The heat of the plasma is also why a "Jacobs Ladder" arc rises. 2) After over 50 years, I now understand why the failure mode of high voltage vacuum tubes (i.e. rectifiers) ends in arcing: the vacuum inside lowers and the breakdown voltage is reduced. So even though the operating voltage is the same as when the tube is new, after several years of minute leakage, the tube will occasionally arc. With more time, the arcing increases, ending the useful life of the tube.
Is there any way you could show us in your vacuum chamber if Sodium Potassium alloy (NaK) would attack aluminum similarly to gallium or possibly mercury? I think Cody mixed some NaK with Galinstan and tested it on aluminum but I'm curious what just NaK could do
Check the vacuum with different gases as you pull the vacuum down when you let the vacuum back in suck in a gas like Oregon helium or something and see how that reacts to the plasma
I would get a vacuum chamber but they... _suck._

James hope your well, I wondered if you might do a video on negative ions because when I put smoke/vape in a box it cleared the air completely so does this mean its a good idea to have a negative ion generator in the home? And pollution in the air if you had a metal plate that was just cold enough to produce water droplets would the pollution get trapped in the water I was thinking of building one out of Peltier's but I have no way of seeing if the pollution is in the water or not. Keep up the good work cracking channel you have developed.
got high and had this thought. thanks for the video
you should try to go below 10-3 bar (using a turbo-pump and a membrane (and/or) scroll pump)
Here is another view of it. Place diodes of sufficient rating to handle the high voltages so current flows only in one direction or another.
a)When a tip is positive charged, electric field lines diverge from the tip electrons are striped from from neutral molecules. Now positively charge ions are pushed away from the tip along electric field lines, with those same positive ions also pushing against the positive charged tip.
b)When a tip is negatively charged, electric field lines diverge from the tip. Electrons are either ejected and or charge neutrally charged gaseous molecules. Now negative charges are pushed away from the tip along electric field lines, with those same negative charges pushing against the negatively charged tip.
Lesson learned is that thrust is generated when the tip is either negatively or positively charged from electrostatic pressure pushing on the ions and the direction of diverging field lines pushing ions away from the tip. The question is if the current is alternating, wouldn't the ions just reverse direction providing no net thrust. and given the fact that it does spin, does that really mean it is not due to electrostatic thrust, and must be caused by thermal expansion? No.... the ions are electrostaticly pushed in one direction away from the electrode. Since the ions are accelerated in mostly one direction and are slowed down through collisions with neutral molecules, and other ions with the same charge that have been slowed down, they tend to hang around a while little longer imparting more electrostatic force on the tip, as demonstrated with not as strong of a vacuum pressure. Then for a period of time the voltage drops below that which can ionize the air and the ions and tip travel further distance away from each other. In time the voltages reverses and eventually reaches a voltage that can ionize again with nothing but neutral gas molecules near by to be charged and repulsed. Distant ions of opposing charge are not as effected (do not change their momentum as much) because of their distance from the tip. The result is net thrust in one direction even with alternating currents.
What is the source of thermal energy in a plasma discharge and does it have a direction? I am venturing a little beyond my sure understanding, but in a lightning strike, some thermal energy is caused by the acceleration of ions in a particular direction, they bump into neutral atoms exchanging momentum in the random collisions in front of them that in turn slowing down the ions down. Furthermore, as with all conductors, electric current causes a magnetic field. In a lighting strike, billions of amps are discharged in a fraction of second. Some energy from the discharge gets stored in a magnetic field and is released when the current stops. The ions' (unbalanced electrons) will be magnetically have fields aligned at a right angle to the direction of current flow. Those ions most strongly repel other ions in the plane at 90 degrees to the current flow. The magnetically constrained ions will jump in temperature with a magnetocaloric effect over neutral molecules. The newly aligned magnetocaloricly heated ions have a lot momentum to impart to neutral molecules and ions in the plane of their magnetic field 90 degrees from the flow of current.
Science is just math disguised as something interesting... Change my mind - Edit: This was a joke lol didn't mean for everyone to argue
But maths is already something interesting

*_NO MATH IS THE WORST THING EVER MADE!!!_*
That's amazing quote
@@KyrusR Why? It is very interesting as well as easy. I always get full marks in my exams in C.Maths and O.Maths.
@@KyrusR, ur so right. 🙂
Science is my fav subject so I love this channel
What would happen if you had a pair of open scissors that had blades a lightyear long, tips a lightyear apart, handles below the fulcrum are the size of that of normal-sized scissors... and you closed them in a perfect vacuum with no atoms or photons to cause drag on the blades as they closed?
I would imagine they would either have to break the speed of light to match the speed at which the handles meet or some unknown force would impose resistance on the blades to keep them from breaking that rule (and making the handles REALLY hard to close).
vaccum narrows down the particle count density of the air making them longer and more subtle to change, as less resistance in the chamber.
at 4:10 when its spinning i can see the light of the sparks draw a circle but its not an continuous line. It seems like several constant width lines with dark gaps between them.
Is this caused by the frame rate of the camera and the coil's frequency? Is this visible at naked eye? If so, you could plug in a frequency generator to the tesla coil (if it can play music...) and see what visual effects it shows.
awesome ☺
Very naice!
NOW TESLA COIL SERIES STARTED IN ACTION LAB!!..
AMAZING............
I really like science stuff and know about new things
You should make a video on Laminar flows!
But wil it spin faster at higher pressure ?
(Love youre vids)
You have one large magnet and note the polarity so that you know which side is north. If you break it would the polarity flip on the new piece when you place them parallel or would they be the same? If they do then isn't "opposites attract" wrong. Maybe you could do a video explaining it.
Thank you for the lesson.
Could you please make an experiment with a induction heater and Steel in the vaccum chamber?
“Thats so kewl” -The Action Lab
Action lab Please try putting a metal rod to arc it and see if under vacuum, arc's jump longer or shorter ?
You are genius bro ..
This creates a permanent pattern. If you do something once you can do it" Again,a million good times.! after," At 2.8 hahaha
1) The heat of the plasma is also why a "Jacobs Ladder" arc rises.
2) After over 50 years, I now understand why the failure mode of high voltage vacuum tubes (i.e. rectifiers) ends in arcing: the vacuum inside lowers and the breakdown voltage is reduced. So even though the operating voltage is the same as when the tube is new, after several years of minute leakage, the tube will occasionally arc. With more time, the arcing increases, ending the useful life of the tube.
*Nice Ali-A Shirt!*
Is there any way you could show us in your vacuum chamber if Sodium Potassium alloy (NaK) would attack aluminum similarly to gallium or possibly mercury? I think Cody mixed some NaK with Galinstan and tested it on aluminum but I'm curious what just NaK could do
Dear sir how do what do you call an ordinary tesla coil without music kit I would like to buy one. though one that discharges plasma horizontally
I wonder how different kinds of pen will work under vacuum. I haven't found any video about it. Can you please make one?
You are amazing
Check the vacuum with different gases as you pull the vacuum down when you let the vacuum back in suck in a gas like Oregon helium or something and see how that reacts to the plasma
Would it look pretty if repressurized (partially of course) with Ne/Xe/Ar?
