FYI you should flip your LPS bulb upside down, or at least have it on its side. Sodium dripping on the electrodes and alloying with them is basically the only failure point of the bulbs. If you use it upside down or sideways it should last pretty much forever.
That’s good to know! I will do that from now on
He's right, also hi yall
hi
@@mobeingmo 🔴 What Is Islam?
🔴 Islam is not just another religion.
🔵 It is the same message preached by Moses, Jesus and Abraham.
🔴 Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God.
🔵 It reminds us that since God created us, no one should be worshipped except God alone.
🔴 It also teaches that God is nothing like a human being or like anything that we can imagine.
🌍 The concept of God is summarized in the Quran as:
📖 { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4) 📚
🔴 Becoming a Muslim is not turning your back to Jesus.
🔵 Rather it’s going back to the original teachings of Jesus and obeying him.

I agree 100%, preferably horizontal as you don't want too much sodium collected into the "U" bend either but if it's a lower wattage bulb, it probably won't matter.
If you use multiple tesla coils out of phase, it is possible to get metal vapors to take shape of a galaxy or a star under right conditions, similar to how physicist Winston H. Bostick did back in 1956. Would be a very cool experiment to see if you succeed at forming fractal galaxies from plasma.
Experiments like these are intriguing. Apart from it being intriguing, it really provokes our deep-rooted curiosities.
Pls show the measurements eg degree Celsius thnx
This looks SO cool! Just seeing how the bright orange glow changes, moves and flickers/pulses is fun.
You had my attention at “Torch” and “Tesla Coil”. High voltage and fire are the key ingredients for a good science experiment.
now this is the type of science i wanna see
The single wavelength also cuts through mist and fog which was part of the original decision to use these for street lighting. LED just lights up the fog and reduces visibility even more. This is what happens when you no longer have the engineers with the original knowledge.
It really depends on the LED that is being used, also there's plenty of places in the world where dense fog is extremely uncommon.
@@_shadow_1 Depends on the colour of LED tbh.
LEDs come in a wide range of colour temperatures commonly from 2700K to 7000K. They are now commonly used on highways which experience high fog levels.
@@_shadow_1 The same principle (Rayleigh Scattering) that makes LED light scatter within fog particles and illuminate them happens within the eyeball. When this scattering happens in the eye it creates disability glare, a physical wall of scattered light within the eye. Just about everyone has stories of being blinded by LEDs while trying to drive at night, with at least 1 fatality being reported when a driver hit and killed a pedestrian that he had no way of seeing after being blinded by the headlights of an oncoming car.
@@SimonBrisbane They are, to detrimental effects. The problem with LEDs is that high-efficiency LED chips only come in blue. "White" LED lights work by using a phosphor to broaden the wavelength into a fuller spectrum, the warmer this spectrum gets the less efficient the LED gets. By the time an LED has a spectrum near 2200K it's less efficient than Sodium lights, making LEDs in their current technological state pointless for outdoor area lighting.
That was a real Beavis and Butt-Head laugh at 2:11 😆
Hey! I think you should have a valve before the vacuum line (like in a Schlenk flask), or at least have a cold trap before the pump. Sodium vapour can be dangerous for pump internals
I got to see a sodium lamp once in my school physics lab when we were learning about diffraction gratings and spectrometers. Really cool stuff
Almost all the streetlamps in the UK used to be sodium vapour lamps.
I love how authentic your reactions are 😂
Actually the coolest video I've ever seen from you over the years ❤👌
Thank you, always nice to see plasmas
@The Action Lab *_Another amazing video!_*
Great experiment ! I also wanted to try it. I originally wanted to create a low pressure sodium lamps with a glas tube, Helium, and sodium metal.
What about Pottasium, Litihum etc ?
@@great__success Well, they would be a special discharge lamp.
That’s another great one !!! 👍 Thank You
Super! Thank you very much!
Another question I never asked myself, but once again I really enjoyed the video 😁
I love your videos! Can you explain how it works the glass that turns opaque with electricity?
oh wow that is awesome
Just make sure you put enough Na in the glass vessel so you wouldn't start drawing the Na from the glass. You can get a similar effect even with just a glass vessel by causing the Na from it to evaporate but that would obviously damage the glass or at the very least cause enough internal strain to make it weaker. I think NileRed had a video of microwaving Al foil in a glass jar which was enough to cause the Na from the glass to evaporate and start shining in its usual colour.
I don't think any vacuum has the ability to "draw" Na from the glass - in NileRed's experiment, the hot plasma was in direct contact with the glass, which gave it that color...
Btw theres like great amount of physics behing generating plasma as shown in video- from wiki: "In field ionization, electrons are removed from a species(Sodium in this case) by quantum mechanical tunneling in a high electric field(generated by tesla coil), which results in the formation of molecular ions(plasma)"
@@great__success Yes. Vacuum itself can't draw significant amounts of Na. So you need to get the glass really hot. Like with the blowtorch here or with the plasma generated by the interactions of EM waves and the foil in NileRed's experiment.
hmm yes words
As a former science teacher at the high school level make some nitrogen triiodide and see what sets it off. That would be a great demo assuming YT approves!
Nitrogen tri-iodide can be remotely detonated with a violet laser pointer (but not red or green). Otherwise, it is one of the most oft-repeated demonstrations on YT... Try Search.
you need some didymium glasses (that way you could prove it's "sodium's colour" by filtering it out).
they're super cool if you ever need to melt borosilicate glass and see what you are doing.. but kinda pricey..
I think it's cool that he's just a big a fan of his vids as the rest of us
Fun fakt: East Berlin used low pressure Sodium Lamps and west Berlin used Metal Halide(wich are white) and its still visable on satellite pictures.
Love your videos ❤️ 😍
It'd be fun to look at the plasmas through a diffraction grating. You can see the different spectra in the reflection from a CD if you don't have a proper grating.
Yay, my chart has been featured in the video, nice :D
Gallium can technically be used in a variant of metal halide bulb that's basically also a hybrid of high pressure Sodium bulb, a Ceramic Metal Halide bulb, as they're designed to run hotter than the typical Metal Halide bulbs, however it would add too much blue, possibly skewing the color rendition index of the light. I have the ceramic metal halide bulb in my modded Halogen spotlight, it's an interesting bulb, and excellent for remote photography at night if I need some artificial Sun for good shot of nature (probably with astrophotography tossed into).
4Dfryd
looks flammable
Was going type a comment about how all you did was make a low pressure sodium lamp, then you said it yourself.
It would be pretty cool to make a lightsabre with this technique
Wearing your watch on the same arm you move the Tesla coil with? Is that safe? Is that bad for the watch?
It is pretty cool of the science behind this experiment! It looks like a fire tornado in the glass. This involves TONS OF CHEMISTRY
Mate, this one was very cool.
Wow! Amazing video sodium be like and action lab also be like😊😊👍👍
Awesome 😍😍
Wow that was so fucking cool, thanks for sharing!
In aircraft engine intake/exhaust valves, they are filled with Na to aid in cooling.
"A single wavelength of light" The sodium spectrum is dominated by the
bright doublet known as the Sodium Dlines at 588.9950 and 589.5924
nanometers.
Wow really kool ❤
I love your vacuum chamber
@TheActionLab I am confused isn’t the boiling point regulated by the partial pressure of sodium in the air rather than the total atmospheric pressure? If so then how much partial pressure sodium metal really exert in 1 atmosphere of air?
How did you prevent the sodium vapor from being sucked into the vacuum pump?
Wow, is sooo cool ♥️🍀😍
Is there any other metal that is worth experimenting with in your garage? Can you produce other monochromatic colors with this?
Does it pull electrons back as it cools back for phase change?
It would be nice if you also gave us metric measurements!
Every substance has a vapor pressure, meaning you'll get substances that are liquid or even solid yet have atoms making up a vapor contained in a partial vacuum inside. A sealed glass tube. Try lead, potassium, lithium, mercury and others.
Once they start ionizing the ionized gas temperature will skyrocket and knock more atoms off the solid metals.
Now you should use it to show off some black fire. Since you have it there anyway, would make a nice short.
That is a really cool sponsor.
Do more on monolight!!! 😮
your channel is one of the best scientific youtube channels. therefore, I expect you to start using Celcius more instead of Fahrenheit.
Heyy action lab,
It was my school science fair last week and the topic was sound so I quickly went to my chemistry lab and borrowed a test tube and did the sound from heat experiment. It took me a few tries but I eventually got it working. All my teachers and friends were amazed to hear such a loud sound from a test tube.
Thankyou soo much for that video. I mentioned about your channel
Probably means "science fair" and NOT "science fail"...
@@peterpcampbell9485 Thanks for the correction lol
Wouldn't the energy transfer from your Tesla coil be more efficient if you put some metal sphere on top, to get rid of all the sparks?
For an O’Neill cylinder in orbit, You should be able to take any metal, turn it into plasma, and throw it out the back.
That would require most of your cylinder to essentially be a capacitor/battery. Preferably one that didn’t slosh around.
You could make an O’Neill cylinder a battery with just flywheels (at the end/qand capacitors throughout the body.
You should also be able to “Brake” the orbit of the cylinder using the mass, just make sure everything‘s secured (doesn’t have to be that violent, it just has to be enough to get you a push in the right direction)
so if supper heated steam where added then what? as sodium and water is bad wI'll that be explosive?
Love the channel - I watch and learn with every video! I've noticed you advertise Established Titles - many of the large CZcamsrs have fallen for this - its a scam, see the video from Dave Jones (EEV Blog) or Scott Shafer.
Wonder if the plasma getting sucked into the vacuum pump will extend or degrade the oil?
Would the electric field generated by the tesla coil also affect the body of a person in the vicinity? What frequency range is involved?
Cool, a really bad DIY sodium lamp! Haha
Very cool!
Can you do a video on a Rodin coil/ Vortex coil?
Nice light bulb !
Is it just me or you literally made a low pressure sodium lamp? :-)
EDIT: 3:45 : Hahahaha so it's not just me :-D amazing!
Would the same thing happen with Rochelle salt? Just asking because it’s piezoelectric. I like the piezoelectric effect.
Wow. Didn’t know it make objects appear monochromatic. No wonder the grow freaks are so strict about which particular light is used (either High pressure sodium or metal halide) during the vegetative and flowering phase when growing vegetables plants. Nice explanation on how exactly sodium based lamps works.
NaCl... table salt, the most common molecule containing sodium I'm aware of... so would vaporizing NaCl in this manner release the sodium resulting in similar ways... (iodized or not?).
Now imagine we coated the Erlenmeyer with a fluorescent coating and mercury.... oh wait... we got a fluorescent tube now.
Great video. Please always put metric values on the screen if you wish to quote imperial values like Fahrenheit. Literally most of the world is metric.
Can you please mention Celsius with Fahrenheit . Because it's making some including me hard to understand.
Where can I get one of those sodium vapour lamps?
Is sodium vapor diatomic, and how does that affect ionization energy? Is sodium vapor opaque or was that just the deposition on the glass walls?
If you attach an electrode that goes through the glass, and into the vacuum chamber where the vapor cloud is being turned into plasma, and then measure the voltage and current with a voltage multi-meter, what will it show? Could you charge up capacitor banks this way, with a water wheel and permanent magnets? Would there be no advantage to lighting up the plasma first? Does the plasma cause a useful increase in voltage?
Hey, you might want to try this with Potassium, NaK, Quicksilver, Cesium or Francium too...
They all have a relatively low vaporisation temperature.
What about Galinstan?
Could you do an experiment with bismuth crystal?
Hello. I have suggestion, what if some liquid is cannot turn into solid, for example water if you put in freezer for a long time but it didn't turn into ice, is there something like that? I'm curious because I have an e mix liquid from beauty products and I put it in the freezer all night but it didn't turn into ice in the morning
It needs to be colder
@@vivimannequin I did that and adjusted the freezer to a high volume but not gonna change and the beauty products are like lime, I just added something like powder and the texture became liquid
What if that high voltage works on the inside of the butane tank? Maybe that is not a problem since the butane is liquid in there?
Three different problems with the thought of high voltages inside butain tank.
1) metal container creates a faraday cage preventing differences in electromagnetic potentials inside the tank
2) There is no oxygen inside the tank so even it were sparking and arcing inside the tank, there would be no flame orcexplision because there is nothing to oxidize the fuel.
3) the contents of the tank are under pressure. You need a partial vacuum, very low pressure gas. The reason is ions responding to changes in the EM field need to have time to accelerate in order to knock electrons off and make more ions cascading into a great many ions that can inturn respond to the changing EM fields. But because under you pack a bunch of butain molecules into a small space, under pressure, if one were ionized, it would have far far far less time to accelerate , and not having enough energy, would be unable to ionize more butain molecules.
You should do this again but add some strong magnets
I did the math and 27.5% of this video is sponsorship.
Hello Action Lab! Can you do it with potassium instead of sodium ?
10/10
ok, thats how lps bulbs work. but what about hps bulbs, that are used for grow lights?
Well, they are a bit different. When the Arc turns the sodium into vapor it pressurizes the arc tube. This increases the chance of a electron hiting a Na atom and rip it off. So HPS lamps also have a ceramic arc tube which is compered to LPS small arc tube. As a lamp collector, this is the difference i can tell you. Also on my chanel i made a video about showcasing a HPS bulb and plan to do a documentary about HPS light.
Sodium lights are great when its foggy, far less glare.
I always new that you can boil metal but I've never seen it.
What would happen if you used NaK alloy?
Action Lab: "So if I'm going to do this in my garage, it needs to be a metal boiling point..."
Me: "Mercury!"
AL: "Now a metal with a really low melting point is gallium, it has a really high boiling point.... So lets try to use a metal with a much lower boiling temperature..."
Me: "Like mercury!"
AL: "Like sodium."
I have a problem 🤣
So you want a fluorescent lamp?
@@vivimannequin YES! 🤣
What happens to the sodium as it's being processed by the vacuum?
Can this be done with Noble Metals?
Established titles was actually exposed to be a scam
Nice, your Tesla coil is huge, now I feel that mine is just a toy !
Sir how can we melt a shaving blade
Next video, metal plasma sabres
Damn guy has the yondu type hair cut from guardians of galaxy 😂😂
Is it really high voltages or high frequency. As a gas the molecules are more acceptable to magnetic fields. As long as the Tesla coil oscillates. It will admit Light
I was wandering when you cut the sodium... What would have happened if a sweat drop fell on the sodium?
A low-pressure sodium lamp, in this case very low pressure! When I were a lad, the streets were illuminated with these, and their weird monochromatic orange light. In fact very monochromatic, you had no chance at all of telling what colour eg a car was. But we managed fine, maybe it was even a nice warm welcoming colour. I dunno, at least you could see.
Now it's mostly white LEDs. Kids today, don't know what they're missing!
It's like the sodium vapor lamp
4:23 just noticed the Kamski's look from Detroit: Become Human :)
