I believe the ball at 4:40 was rotating around 30000+ RPM for a moment! The pitch was about C5 (523Hz) so 523 revolutions per second, times 60 (60 seconds in a minute) gives around 31380 RPM. Edit: I'm assuming the sound is created by the pressure waves due to the jet (1) of the ball. And judging by the previous results (around 15000 RPM) it makes sense.
This is what I got too. I saw a gues for 60000 but I think that's an octave high; this is about a c5, not a c6. Trying to think of pop songs that have c5 and c6 as a major. C5 is Whitney houston in i will always love you (it's a b5 but this tones between the 2. So pretty close). An octave higher would be 60000 but that's way too high
It was around 31,395 RPM. In the one run. I measured the frequency of the sound and multiplied by 60 to get it in RPM. (edit: I measured it wrong the frequency was around 523hz.)
@@PinkeySuavo this exactly! A smooth ball rotating shouldn't produce differentiations in acoustic pressure. So 1Hz may very well not be one rotation. It could be something else.
@@PinkeySuavo if there is a hole on the side of the ball where the jet comes out from, and you can even hear it in the low frequencies, it's obvious that for the microphone, the variations in loudness would repeat once ever one rotation. It makes sense.
7:59 "You use more energy making the liquid nitrogen than you get back out of it in the engine" Ok but this is true of EVERY energy storage system. A 100% lossless energy storage system would be world-changing, it doesn't exist. The real issue in powering vehicles is energy density, since vehicles actually need to move the weight of their energy source around, that ratio is critically important.
@@DrDeuteron You're basically turning everything except the liquid nitrogen into a battery, then extracting energy from the system by allowing everything else to warm the liquid nitrogen.
@@Frommermani would argue that the nitrogen is still the battery, it just happens to store a "negative energy" from the ambient temperature and also where it is then released in the phase change. Either way, it's still just a temperature gradient. Think about how AC electricity has potential in both positive and negative voltage compared to ground.
@@DrDeuteronbasically how thermodynamics works is that any place there is a difference in temperature, you can extract work from it. So if you have something extremely cold like liquid nitrogen, you can take some of the heat energy being transferred into it from the ambient environment and convert it to work. It's like how a ball on top of a mountain has potential energy if you consider zero to be sea level, but a ball at sea level has potential energy if you consider zero to be the lowest point in Death Valley. We can always extract energy from something as long as it has a lower energy state for it to "fall" into.
I built this engine as my science fair project in 8th grade. I entered it in the engineering category. I was awarded the blue ribbon for engineering. I was also awarded a blue ribbon for physics, though I had not entered the category. I used a copper toilet float given to me by my uncle, who was a plumber. I used two copper 90° tubes, which, with the help of my uncle, I brazed onto the toilet float. Water was filled through the threaded hole where the float rod screwed into the ball. We used a simple screw to close the hole. We used JB Weld for car exhaust repairs to attach it to bearings on either side, which were attached at two points to a frame we built. I used a Sterno for the flame. That was 45-46 years ago, and I've been a rocket hobbiest ever since. My grandson and I are building compressed air rocket right now. This is fun stuff!

At 5:19 the levitation fails because the ball is experiencing the Dzhanibekov effect; put simply it wants to spin with the metal piece on the perimeter rather than in the center, so starting it with the metal piece in the center means it wants to flip around and spin around a different axis. To fix this, put the metal around the ball rather than at the top, so the spinning ball looks a little like Saturn. Once you do that, you'll be able to get a lot higher spin rate.
Just to clarify: if your hairy trumpball has only one hole for the gas to escape then the pitch of the sound is mathematically equal to the RPM of the ball. If the tone measures 1000hz then the ball is spinning at 60,000 RPM. (1000hz x 60seconds) If the RUclips frame rate is faithful to your orbanusmeter
To do the audio trick: Import to audacity, then amplify to 0dB. Then go plot spectrum, use super auto-correction. The peak frequency is the base harmonic of the sound. Multiply that number by 60 and you have the exact RPMs. (I used this trick in uni to figure out the speed of turbines without having to use a tach into narrow spaces)
Improvement idea: 1) open the ball and insert a small disc of ferrous material 2) reseal the ball and fill with LN. 3) drop on an induction stove top, heating the ferrous disc without drag.
What happens when the ball melts? Styrene has a melting point very near the temperature of induction stoves, both up to 500° F/260° C. Given the already extreme difference in LN temperature versus ambient air, I don't see much benefit to this added weight, likely imbalance in attaching the disk and resealing, and danger of having a plastic ball stuck to your stovetop, as well as the fumes the styrene and most adhesives would release when heated.

For those who don't know: nuclear reactors are just giant steam turbines that use atoms to heat the water instead of fire, hence the number for steam-generated power. It's astronomically more fuel efficient than most heat sources.
We are moving away from that. Next gen reactors do not use water as coolant, so there is no need to also use that as heat transfer medium to the turbine. Plain CO2 is a great gas to use for heat transfer, it does not have the risk of exploding like water, and by replacing the steam turbine with a gas turbine we can get up to 40% more efficiency from just that change.
@@kingki1953actually that’s pretty much every power plant. The main goal is to make steam that then spins a turbine connected to a generator to make power.
There's no hollow inside ball bearings, so no. :( However, I once found a ball bearing can be caught in the air jet from a narrow nozzle connected to a compressor, and would spin up to crazy speeds! Point the air jet up.
I believe that the bit about why we don't use liquid nitrogen also applies to hydrogen cars. Since we first have to obtain hydrogen, often through using electricity to break down water, and because no process in the physical world is 100% efficient, there's necessarily some loss of energy. And then the car has to convert the hydrogen back into electricity, incurring a second conversion loss
@@Jordan-Tech RUclips is quite careless with comment data. Several other people have calculated it. Look for @PrincipalAudio who has done it well: first testing his method with the tachometer-measured ball.
i love it also when it is explained, why and how the knowledge was sort of ahead of its time- like why they didn't start building steam engines way earlier etc. it is such a clever way to end up answerering not asked questions.
@erner_wisal jojo's bizzare adventure part 7, steel ball run. There's a second power system where they can use the golden ratio to provide the perfect spin. A side character uses green steel balls to throw them with the power of golden ratio and they do much damage. It is not an anime and we didn't get any official release date. We just hope that the author will make an anime for this manga
The other factor of the failure of this engine in ancient times is that there was simply not a lot of potential use for it, although a similar technology also invented by him was used to open door temples. A lot of technology is discovered when there's no practical reason yet. Bayes rule only found use after 200 years from its creation.
@@Plasmacore_V the much bigger problems were relatively primitive metallurgy and lacking precision in production methods. it would have been straightforward to make something like this function as a sort of novelty, but getting it to do useful work would have taken expertise that just wasn't there yet, you need to be able to make properly fitted gears, which is hard enough to do, but making bearings would have been even more of a challenge, especially since the whole mechanism required heat to function, so you'd have to factor that in, make everything fit properly and have it be balanced enough for the whole mechanism not to shake itself apart at those high rpms. just look up how long it took for humanity to go from the first functioning firearms to reaching the level of precision needed to making them with interchangeable parts, that's the kind of precision you need to make a combustion engine, nearly impossible without a powered lathe.
In order to heat the liquid N faster inside the ball I had a few thoughts: 1) warm a metal or glass dish in an oven for a while, maybe a glass bowl that is oven safe and would contain warmer air as well as a warmer surface. 2) along those lines, warm/heat one of those curved mirrors for an Euler's disk. 3) fill a small container with sulfur hexafluoride (SF6) that would maybe allow the ball to float (I don't know the relative densities so it may not work, if it does then you could heat the gas too.) and 4) Taking all precautions, heat a pool of liquid mercury and then put the ball on that ;)
I just checked the frequency of the sound after it was dipped in the water by using Audacity to record my system sounds and played the video and then I put it in spectrogram mode to find the true fundamental and plotted the spectrum to get the exact frequency and it was 527Hz, which means it was 31,620RPM if it only had 1 hole.
Water ice is much hotter than liquid nitrogen. Get a big block of ice, make a dish shape in the top of it, the ball will spin almost friction-less on the ice, and self correct to stay near the bottom of the dish shape. The gas will come out still, just over a slightly longer time, which ought not change much about the peak speed.
Why not use an air vent to keep ball in one place and floating. You know like those toys where a ball stays in one place over an air vent. The air can be hot and also lower the friction for the ball to rotate even faster. Would love to see that
@AKG58Z If any setting on your hairdryer melts a ping pong ball, you probably need a new hairdryer. And most hot air guns can be fun at even lower temperatures than hairdryers.
The high rotational rpm’s would surely cause the ball to leave the air stream. It would be almost impossible to not have the two rotating vectors interfere.
From the pitch, I heard a little more than an octave difference between the time you got 18,000 and 13,000, and that suggests a little more than 2x the speed. Assuming that the 18,000 was not an artifact and you trust it, that would mean the ball was at almost 40,000 rpm. If you trust the 13,000 more, that would mean the second ball was more like 28,000 rpm. This is off the ear test btw.
Small correction to 1:45 "It doesn't matter how fast you're going", this ignores near-luminal speeds, at which point it takes more and more energy put in to get smaller and smaller acceleration out. Nothing with mass can reach c, so there IS a limit.
@@BigyetiTechnologies again, the entire point of The Action Lab doing the experiment the way they did was to see how fast it could go. So why deliberately sabotage that by slowing it down?
See if the Shlomo guys would be interested in a collab on this... Just to clarify: if your hairy trumpball has only one hole for the gas to escape then the pitch of the sound is mathematically equal to the RPM of the ball. If the tone measures 1000hz then the ball is spinning at 60,000 RPM. (1000hz x 60seconds) If the RUclips frame rate is faithful to your orbanusmeter
I noticed something that could have influenced your warm water test. The first time you did it, the dish was almost full of water. The second time you did it, the water was very shallow. I wonder if the reason it bounced out, was because it submerged briefly and the buoyancy launched it out.
@@sslp2525 phonetic Japanese. Google doesn't even know what to do with it, lol. It's like writing English using the pronunciations offered for each word in the dictionary, instead of the normal spelling.
"Liquid Nitrogen isn't an energy source" While true, it's also important to mention that it is used as a monopropellant fuel source in cold gas RCS thrusters on spacecraft (correct me if I'm wrong ofc), going back to the same original principles as those in the Aeolipile. Just because it is energy negative, doesn't mean it isn't useful as a fuel under the right applications.
I have perfect pitch. The pitch the ball made at 4:40 was a slightly sharp C5. I would estimate it to be around 530-535 hertz based on my ear alone. Multiply that by sixty, and you get around 31,800-32,100 RPM based on the sound alone. As another little fun fact, given the average ping pong ball is about 4 centimeters in diameter, that would mean the velocity of its rotational equator was about 66.7 meters/second, or 149 miles an hour.
FYI I am willing to share a couple of my inventions with you if you will build and test them on your show: #1) I made one magnet attract itself towards an iron plate hiding another magnet behind it which then DID IN FACT repel the outer stator magnet making the inner rotor magnet and iron plate continue moving, and I only moved it 1,000th of an inch per second initially using a caliper and watch so I can calculate the forces. I wish I had recorded it! Now I plan to try and build it again but a full motor this time! #2) I think I figured out how to use counter-rotating magnetic weights and 'solenoids' to produce significant propulsive force in air, water, and space craft, with no outer apparent means of propulsion. And #3) If I can build both of these I could build craft which 'fly' through air, water, and outer-space, with no fuel or visible means of propulsion! Also I believe I am very close to answering the errors in equations relating the force of "Gravity" and "Quantum Mechanics", by showing how "electricity" is really just pressure upon space-time in 3D, "Magnetism" is a result of spinning that pressure to create "Dipoles" and "Lines of Force", then "Resonance" is the actual cause of the "Strong Atomic Force" (at the first "Nodal Point" where attractive forces are the Strongest), AND "Gravity" (Everywhere outside of that 1st "Nodal Point"), and the "Weak Atomic Force" is a result of the opposite "Force" we call "Dissonance". Now I have been studying Einstein's Field Equations and Maxwell's and many others (especially that "Stress-Energy Tensor" used to measure "Energy" in a 3D volume, HOW EXACTLY is "Energy" measured, and in which unit? Joules I think is the unit btw, and I think it was Grams for Mass and Meters per Second for Speed of Light, in E=MC^2). So I am willing to discuss that also, with anyone who actually comprehends "Integral and Differential Calculus" and all these equations, which I am still learning right now).
Throwing a weight when you are sitting on a rotating chair is actually one of the best experiments to explain action/reaction. I wish my teacher would have done this in school
Nah, the hero's engine has massive problems that prevent it from being used to accomplish any work. It was an important step toward the industrial revolution though.
You have to remember that leaps in technology seem obvious once they happen. No one in Greece saw potential in the engine, so they never thought to progress its ideas.
I think slave based societies don't have sufficient pressure to invent new machines to replace human labour. In fact having open borders probably has the same effect. You need labour costs to rise to force people to industrialise and if the elite can control labour costs you get stagnation.
i think one fo the cooler things you demonstrated in this video is how that laser that was on the tachometer had enough energy to oinfluence the direction of the spinning ping pong ball. its minimal but that was clear influence
You should try doing it with the punctures angled obliquely not horizontal as seen in here and putting it in a long lab tube with water at the base and see how high it could propel itself upwards.
Thanks. Must be the same concept as the nitrogen used in cars for a speed boost. Now i understand why the wheels turn so fast all of a sudden when activated.
Wow! When you put it in the water and it started spinning super fast, it sounded like it had an electric motor in it because of the noise it was making.
4:37 can I admit that sound is both cool 😎 and frightening 😳 at the same time 😑. Sounds like a very powerful engine 😯. You make the coolest videos 😎. Kind of reminds me of bullets when they ricochet as result of moving at such a fast pace 😎.
Yes based on the pitch it sounds just like one of those high-speed brushless motors. They say they are usually about 100,000 RPM? And some of them 130? It's hard to really say. I know I've exceeded mine and heard that super high pitched whine! I am unable to measure but I do have ears.
Space flight organisations are extremely careful that the astronauts are selected based on the concentricity of their ani. It's little known fact that it is the most important attribute that they are tested for. An eccentric anus can be disastrous as was seen in the "Событие бобов" (Beans Event) on the Russian space station MIR in 1997 , and the "Beans Event" on Skylab in 1973
I believe the ball at 4:40 was rotating around 30000+ RPM for a moment!
The pitch was about C5 (523Hz) so 523 revolutions per second, times 60 (60 seconds in a minute) gives around 31380 RPM.
Edit: I'm assuming the sound is created by the pressure waves due to the jet (1) of the ball. And judging by the previous results (around 15000 RPM) it makes sense.

Hahaahhahhahah😂
Just to clarify: if your ball has only one hole for the gas to escape then the pitch of the sound is mathematically equal to the RPM of the ball. If the tone measures 1000hz then the ball is spinning at 60,000 RPM. (1000hz x 60seconds) If the RUclips frame rate is faithful to your orbanusmeter
For those who don't know: nuclear reactors are just giant steam turbines that use atoms to heat the water instead of fire, hence the number for steam-generated power. It's astronomically more fuel efficient than most heat sources.
So nuclear power is just heating water with extra step
We are moving away from that.
Next gen reactors do not use water as coolant, so there is no need to also use that as heat transfer medium to the turbine.
Plain CO2 is a great gas to use for heat transfer, it does not have the risk of exploding like water, and by replacing the steam turbine with a gas turbine we can get up to 40% more efficiency from just that change.
@@Merecir thanks
@@hypedstocksprices5963 Look up "LFTR" or "molten salt reactor" for more detail.
@@kingki1953actually that’s pretty much every power plant. The main goal is to make steam that then spins a turbine connected to a generator to make power.
can you use it on steel balls?
Bro isn't gyro zeppeli🙏😭
There's no hollow inside ball bearings, so no. :( However, I once found a ball bearing can be caught in the air jet from a narrow nozzle connected to a compressor, and would spin up to crazy speeds! Point the air jet up.
sadly you have to be crippled at minimum
@@eekee6034why you automatically assume he meant a solid steel ball???
@@cbfull you mean there are other kinds???!?
the way you give visual examples as to how physics work and interact with us is amazing.
I think that's a Jojo reference
I believe that the bit about why we don't use liquid nitrogen also applies to hydrogen cars. Since we first have to obtain hydrogen, often through using electricity to break down water, and because no process in the physical world is 100% efficient, there's necessarily some loss of energy. And then the car has to convert the hydrogen back into electricity, incurring a second conversion loss

@@Jordan-Tech RUclips is quite careless with comment data. Several other people have calculated it. Look for @PrincipalAudio who has done it well: first testing his method with the tachometer-measured ball.
It was more than 5rpms

i love it also when it is explained, why and how the knowledge was sort of ahead of its time- like why they didn't start building steam engines way earlier etc. it is such a clever way to end up answerering not asked questions.

Yeah
Is this a reference to something? If so what is it?
@erner_wisal jojo's bizzare adventure part 7, steel ball run. There's a second power system where they can use the golden ratio to provide the perfect spin. A side character uses green steel balls to throw them with the power of golden ratio and they do much damage. It is not an anime and we didn't get any official release date. We just hope that the author will make an anime for this manga
@stavros222 aha, thanks
Thanks!
The other factor of the failure of this engine in ancient times is that there was simply not a lot of potential use for it, although a similar technology also invented by him was used to open door temples. A lot of technology is discovered when there's no practical reason yet. Bayes rule only found use after 200 years from its creation.
Also a huge problem against earlier industrialization was slavery.
A more modern-day example of that is the fact that no elements after Californium have any practical applications except for scientific research.
@@Plasmacore_V
the much bigger problems were relatively primitive metallurgy and lacking precision in production methods.
it would have been straightforward to make something like this function as a sort of novelty, but getting it to do useful work would have taken expertise that just wasn't there yet, you need to be able to make properly fitted gears, which is hard enough to do, but making bearings would have been even more of a challenge, especially since the whole mechanism required heat to function, so you'd have to factor that in, make everything fit properly and have it be balanced enough for the whole mechanism not to shake itself apart at those high rpms.
just look up how long it took for humanity to go from the first functioning firearms to reaching the level of precision needed to making them with interchangeable parts, that's the kind of precision you need to make a combustion engine, nearly impossible without a powered lathe.
In order to heat the liquid N faster inside the ball I had a few thoughts: 1) warm a metal or glass dish in an oven for a while, maybe a glass bowl that is oven safe and would contain warmer air as well as a warmer surface. 2) along those lines, warm/heat one of those curved mirrors for an Euler's disk. 3) fill a small container with sulfur hexafluoride (SF6) that would maybe allow the ball to float (I don't know the relative densities so it may not work, if it does then you could heat the gas too.) and 4) Taking all precautions, heat a pool of liquid mercury and then put the ball on that ;)
I just checked the frequency of the sound after it was dipped in the water by using Audacity to record my system sounds and played the video and then I put it in spectrogram mode to find the true fundamental and plotted the spectrum to get the exact frequency and it was 527Hz, which means it was 31,620RPM if it only had 1 hole.
Bro assembled every JOJO fan
How are you the top comment
Yes
Gyro
this actually happened to me once, when I was an explorer of the ancient world
Water ice is much hotter than liquid nitrogen. Get a big block of ice, make a dish shape in the top of it, the ball will spin almost friction-less on the ice, and self correct to stay near the bottom of the dish shape.
The gas will come out still, just over a slightly longer time, which ought not change much about the peak speed.
Why not use an air vent to keep ball in one place and floating. You know like those toys where a ball stays in one place over an air vent. The air can be hot and also lower the friction for the ball to rotate even faster. Would love to see that
Or a hairdryer, or hot air gun.
Too hard to engineer, the ball isnt perfect, it will be fly away because of turbulence of itself
The hot air will melt that ball
@AKG58Z If any setting on your hairdryer melts a ping pong ball, you probably need a new hairdryer. And most hot air guns can be fun at even lower temperatures than hairdryers.
The high rotational rpm’s would surely cause the ball to leave the air stream. It would be almost impossible to not have the two rotating vectors interfere.
From the pitch, I heard a little more than an octave difference between the time you got 18,000 and 13,000, and that suggests a little more than 2x the speed.
Assuming that the 18,000 was not an artifact and you trust it, that would mean the ball was at almost 40,000 rpm.
If you trust the 13,000 more, that would mean the second ball was more like 28,000 rpm.
This is off the ear test btw.

Small correction to 1:45 "It doesn't matter how fast you're going", this ignores near-luminal speeds, at which point it takes more and more energy put in to get smaller and smaller acceleration out. Nothing with mass can reach c, so there IS a limit.

I noticed something that could have influenced your warm water test. The first time you did it, the dish was almost full of water. The second time you did it, the water was very shallow. I wonder if the reason it bounced out, was because it submerged briefly and the buoyancy launched it out.

Ok this is SWEET! Thanks!
"Liquid Nitrogen isn't an energy source" While true, it's also important to mention that it is used as a monopropellant fuel source in cold gas RCS thrusters on spacecraft (correct me if I'm wrong ofc), going back to the same original principles as those in the Aeolipile. Just because it is energy negative, doesn't mean it isn't useful as a fuel under the right applications.
4:26 taz the tasmanian devil ahh ball
How about using a hair dryer hold it up in the airflow? With a gentle warming effect it can both levitate and accelerate the effect
I have perfect pitch. The pitch the ball made at 4:40 was a slightly sharp C5. I would estimate it to be around 530-535 hertz based on my ear alone. Multiply that by sixty, and you get around 31,800-32,100 RPM based on the sound alone.
As another little fun fact, given the average ping pong ball is about 4 centimeters in diameter, that would mean the velocity of its rotational equator was about 66.7 meters/second, or 149 miles an hour.
Impressively close to the results of an audio tech who measured carefully.
@@eekee6034he read the top comment then made this crap up. Hes a nobody
DAAAAAAMNNN. Your estimate was *bang-on.*
This is so rad! I never would have thought of this experiment.
Gyro Zeppelin being exposed 😂😂😂😂😂😂😂😂😂😂😂😂
FYI I am willing to share a couple of my inventions with you if you will build and test them on your show: #1) I made one magnet attract itself towards an iron plate hiding another magnet behind it which then DID IN FACT repel the outer stator magnet making the inner rotor magnet and iron plate continue moving, and I only moved it 1,000th of an inch per second initially using a caliper and watch so I can calculate the forces. I wish I had recorded it! Now I plan to try and build it again but a full motor this time! #2) I think I figured out how to use counter-rotating magnetic weights and 'solenoids' to produce significant propulsive force in air, water, and space craft, with no outer apparent means of propulsion. And #3) If I can build both of these I could build craft which 'fly' through air, water, and outer-space, with no fuel or visible means of propulsion!
Also I believe I am very close to answering the errors in equations relating the force of "Gravity" and "Quantum Mechanics", by showing how "electricity" is really just pressure upon space-time in 3D, "Magnetism" is a result of spinning that pressure to create "Dipoles" and "Lines of Force", then "Resonance" is the actual cause of the "Strong Atomic Force" (at the first "Nodal Point" where attractive forces are the Strongest), AND "Gravity" (Everywhere outside of that 1st "Nodal Point"), and the "Weak Atomic Force" is a result of the opposite "Force" we call "Dissonance". Now I have been studying Einstein's Field Equations and Maxwell's and many others (especially that "Stress-Energy Tensor" used to measure "Energy" in a 3D volume, HOW EXACTLY is "Energy" measured, and in which unit? Joules I think is the unit btw, and I think it was Grams for Mass and Meters per Second for Speed of Light, in E=MC^2). So I am willing to discuss that also, with anyone who actually comprehends "Integral and Differential Calculus" and all these equations, which I am still learning right now).
3:53 so fast that the black side was blurry looked like a gas giant for a second
That spin up sound is so rad.

Throwing a weight when you are sitting on a rotating chair is actually one of the best experiments to explain action/reaction. I wish my teacher would have done this in school
Crazy how we could have had the industrial revolution 2000 years earlier, but greece decided not to
Nah, the hero's engine has massive problems that prevent it from being used to accomplish any work. It was an important step toward the industrial revolution though.
You have to remember that leaps in technology seem obvious once they happen. No one in Greece saw potential in the engine, so they never thought to progress its ideas.
I think slave based societies don't have sufficient pressure to invent new machines to replace human labour. In fact having open borders probably has the same effect. You need labour costs to rise to force people to industrialise and if the elite can control labour costs you get stagnation.
The industrial revolution was a mistake though, Greece made the right choice imo. 2000 extra years of unpolluted, nicely paced, happy lives
Because of the slavery, you dont need to automatice work having slaves
wow, how interesting, loved it
_Takes, "LET IT RIP!!!!!" to the EXTREME!!!_
the fact that it was spinning SO incredibly fast that it almost flew is crazy 4:37
Average person : Earth is flat and space isn't real
Random Greek tinkerer from 1600 years ago :
That was fasinating. The speed incredible. The sound was awesome.
"OMG Its works"..........."Holy cow i can't stop it"
i think one fo the cooler things you demonstrated in this video is how that laser that was on the tachometer had enough energy to oinfluence the direction of the spinning ping pong ball. its minimal but that was clear influence
Or he was following the jittery movement of the ball with his hand after a few practice runs, to keep the tach in the right place.
IS THAT A JOJO REFERENCE

You should try doing it with the punctures angled obliquely not horizontal as seen in here and putting it in a long lab tube with water at the base and see how high it could propel itself upwards.

One of your COOLEST videos! Thanks for all the great work!
My tachometer read 80085 😊
Check it against the 13000 RPM run, you'll probably see 32,500 RPM. :) Always test your method
Yes based on the pitch it sounds just like one of those high-speed brushless motors. They say they are usually about 100,000 RPM? And some of them 130? It's hard to really say. I know I've exceeded mine and heard that super high pitched whine! I am unable to measure but I do have ears.
This also happens to astronauts who fart in space.
