I like how he just casually starts the video with 'hey everyone today im going to be blasting a cloud chamber with electrons'.
Yeah that's normal
@Not RickRoll 👇 report
Imagine one day he will say, " hello everyone, today am going to nuke a city and we will see what is going to happen to all the people and buildings" 😂
I did a double take when he casually mentioned using a uranium sample at 4:30.
Lol yeahh
Just love the way he turns theories into practical in such simple way.

You can also inhale the alcohol to get fucked up - it lasts only 5 minutes and it's very bad for your brain. Of course I'd never

*furiously inhales alcohol
And most of them are just stolen from some other RUclipsr
@@Noam-Bahar yeah both spam and unwanted commercial they are soo annoying
Gotta love them cloud chambers. Great explanation on how the path can inform you of particle type.
Plasma,watching action lab 🤩
Hello
When is you new video coming out??
@@attadarshimeshram7136 Working on the new video now. It is taking tons of time, because the experiment isn't working. But, tons of drone footage :P
Hi 👋🏽. Question for all you smart people here .. is it dangerous (wavelengths) to be between all the people using their phones at the same time??
I am a very addictive person by nature. (Omg I feel embarrassed).
So I avoided the smartphone as long as I could. And now since I have one.. I can’t stop looking for information on everything at RUclips. It never ends.. That mixed with my sleep disorder (I don’t sleep every night and when I do only 2-3 hours).
I do keep looking at things on RUclips sometimes > than 15 u 🤭.. omg I am so embarrassed . But I really like a genuine answer?!
My hand turns hot - like it’s f*cking microwaved. Is that possible?? Sorry I know that you find me stupid. If someone please could/ would answers?! .. Thank you ..
Few months later: Hey everyone today I'm gonna create a black hole to slow down earth's rotation
how would that even work?
Technically he could, though we would need to either have the black hole orbiting us... or us orbiting the black hole (much more likely). If the black hole was stationary relative to the earth, the it would pull the same on both sides of the earth and thus any slowdown caused by the gravity at say 3 o clock on the earth, would be counteracted by the black hole pulling at 9 o clock speeding it up.
Oh crap! I can't stop it.
@@paprukas lmao
With a smile on his face
I had no idea we could observe particle movement with the naked eye! Also, how incredible is it that something as small as an Alpha particle can disturb space this much? Really highlights how dangerous radiation can be at high levels. Like millions of tiny bullets being fired in every direction.
Cloud chambers were how people studied particle physics way back before we had particle accelerators. Even today, ironically, we dont "see" the particles (or their effects) to detect them. They are detected using magnetic fields and other instruments and then visualized using a computer.
@@Ddub1083 exactly. Our concepts of what occurs on the atomic and subatomic levels are not yet known. That's why there's still so many gaps in our knowledge, we really can't understand what we're seeing.
@@bland6004 ummm we actually do in fact understand what we see. He even goes into an explanation of what we are seeing is due to the ionization of particles of the alcohol in the air which leads to clumping and then condensation on them. Not sure what you mean by we cant understand it when it was literally explained what was happening and why.
Thank you for articulating this comment better than I could have! 👍
@@Ddub1083 and I have Carl D Anderson's copy of Goldstein on my desk. I used to have Willy Fowlers, too...but someone boosted it.
When your blasting with the nail, there seems to be an equator or something where the cloud doesn't appear. It would be cool to see this phenomenon explained/explored.
yes I am not sure why that happened. There is a clear line in the center of the circle that persists even with a lot of turbulence. I will have to look into what could cause that
That “equator” seems to prefer a certain orientation…I wonder if the fast moving electrons are reacting to an ambient electromagnetic field, possibly due to the high voltage generator attached to the cube. In that case, moving the generator should cause a corresponding movement in the preferred equator direction.
@@TheActionLab
Could it be that in that region ions are created at rate much higher than they condense there ,and these get pushed out due to repulsion .
We should also check the phenomena by reversing the polarity.
@@adrien5568 I guess it would work in same way , a clear region in center.
Things I want to see next to a cloud chamber: x-ray gun (like the one Kreosan's channel built), and a nuclear fusion reactor.
nuclear fusion is highly unstable and it is not possible yet to contain that energy so nuclear fission is a better idea but still not a good idea
@@NVSParineeth I mean a Farnsworth-Hirsch Fusor, those are easy to diy
@@NVSParineeth well guess what, 5 G is also highly unstable and the radiation in 5 G is NOT contained!!! 5 G is already harming us and yet we do nothing about it!!!
I'm a physics teacher. My department has and expensive and complicated cloud chamber that had never ever worked properly. I'll definetly be trying this method!
Probably because they have strict rules on what material can be used, and is barely putting out any particles.
The cloud chamber is my all-time favorite experiment ever because it’s so simple and so incredible.
Until now, I've never actually known how the trails in the cloud chamber are formed by ionising radiation. Thanks a lot ,James!
5 G is like artificial backround radiation added onto normal backround radiation from sun. THAT MEANS 5 G IS WORSE THWN THE SUN WHEN IT COMES TO RADIATION EMMITED. NO ONE CAN ADAPT TO 5 G RADIATION YET WE HAVE ADAPTED TO SUNS RADIATION OVER THE YEARS BY MAKING SKIN COLOR DIFFERENT.
@@insectbite1714 Actually 5G, along with other forms of radio communication are actually quite safe. The "dangerous radiation" that we've all heard of are gamma rays, X-rays and UV. Virtually all wireless communication and connections use wavelengths well below that threshold. The only thing you have to really have to worry about is your phone overheating 😉

@@insectbite1714 Deleted? I still see your comment here
James actually made a video regarding this issue: ruclips.net/video/nKPw-dnxZTo/видео.html
We're blessed with another masterpiece by James. So when do you collab with The Slow Mo Guys?
I wish my school have such teachers
Who has such good luck ?
Just imagine if this guy and the SLO mo guys did a collab.. it would be epic..
Wonder if they could catch one of these particles traverling through the cloud chamber?
Several have posted that, the things is: radiation in slow-motion looks like radiation not in slow motions. That's life at 0.94c
@@DrDeuteron what about these cammeras that can capture light moving?
@@yaykruser LLE-pCUP? that's a whole nutha level. There is dark field imaging of tracks: en.wikipedia.org/wiki/Dark-field_microscopy#/media/File:NuclearTrackPaper02chromiteA.jpg
@@DrDeuteron Yeah, but these things arent videos, I was more thinking of this :ruclips.net/video/snSIRJ2brEk/видео.html
Another Question: Shouldnt these particles slow down very fast? I man thats an alpha particle with the mass of a Hydrogen atom moving drops with billions of molecules.
That would be the real world comparison of an ant bumping into tanks and making them fly away.
Is there a hydraulic jump in the cloud expansion when your blasting it with electrons? The cloud expands quite rapidly at first and slows significantly almost like when you pour water on a surface. It expands rapidly outward in a thin, turbulent layer at first to the point of the hydraulic jump where flow slows becoming much less turbulent. The cloud looks to almost have a similar behavior while blasting it with electrons.
Another possible explanation, the ionic wind is pushing a lot of air towards the bottom plate, which is colder and also provides a nucleation side
this is by far and away the best video ive seen on your channel. more practical particle stuff !
VERY informative. So happy and grateful that you make these videos! I’m learning so much.
Learned something new today. I've seen these vapor chambers before, but I didn't know that alpha, beta and gamma particles look different in these chambers. Thanks.
With the HV needle, you can also see ionic wind, which is the clear flow you see
For some reason i read HIV Needle,lol
I happen to own a Carl-Zeiss "Zebra" Pancolar lens made in 1950s-60s which has coating made of Thorium. Yes, its slightly radioactive and decays emitting Alpha particles.
For some time I wanted to make vapor chamber to check it :D
btw: the beta particles being "buffeted" by air molecules is a bit misleading. It's really small angle Coulomb scattering from the atomic nuclei (molecules and atoms, not so much). The phenomenon is called "Multiple coulomb scattering", and the defection angle grows as a random walk away from the initial trajectory... after traversing a distance "x", the angle (in radians) grows as sqrt(x/X0), where "X0" is the well studied & tabulated "radiation length" of the material. X0 length scale over which a high energy electron losses its energy (3 meters in air).
So true, in reality 5 G particles are actualy Covid particles that are non-living yet dangerous. The Action Lab was sold out to 5 G companies that destroy nature (sigh)
Wow that was really good work! Could have watched that for ages.
Experiments after experiments, it only gets better. Amazing channel
VIDEO IDEA: Can a tiny object break the sound barrier easier than a big object such as a jet?
I think these are called diffusion chambers, cloud chambers have a sudden volume expansion mechanism which creates supersaturated vapor then condenses areound the nucleation sites.
Wow thanks man!
I commented on your last video asking for this cloud video!
Does that blast from the nail cause thrust? Could that be used in the vacuum of space?
Absolutely astonishing. Bravo 👏🏻
Best video yet. I had no idea cloud chambers were so easy to make!
Your channel is so interesting to watch. Keep up the good work.
Put a strong magnet near the chamber (for example two magnets on both sides). It should bend alpha particles to make arcs or even spirals. It would be awesome to see spirals of charged particle radiation!
hey action lab just a small suggestion to u, if u put in some slow mo shots of the cloud chamber getting blown apart by the high voltage, ur video wil lbe exemplary. lots of youtubers do it and it increases content by a lot. hope u try it:)
you can slow mo it yourself using youtube.
I'd love to see a CRT electron gun fired into a cloud chamber. Would it form any sort of picture, or pattern?
5:25 of the invisible of wind between eye storm funnel of a tornado or solar wind from different angles of force. Nice cloud chamber of platinum color of ultraviolet uranium.
I like how you used the sponsor product and recommend it later. Definitely makes it more trustworthy
A lot of the time I feel like you sold out your science to the advertisers, but today I felt the science was for it's own sake, and that made me very happy.
He sold out his science to 5 G companies to promote cancer causing 5 G.
Nice expriment , will you get a spiral trajectory if you put that cloud chamber in a magnetic field.
There are not very many channels that get people excited about science the way yours does! My brain never stops (lol) and I wish I had the time and resources to do all the experiments I think of/want to do (and the stuff I want to build)!
Hopefully, once I start feeling better I can get things back on track. I think the past two years have been a disaster for pretty much everybody.
You did an incredible job explaining cloud chambers! One of my favorites is the classic one with uranium ore :-) being able to see radiation being emitted from a rock is pretty incredible!
Naturally, I do not know you (lol, wish I did!) but thank you so much for having such an incredible Science Communication channel!!!!
Your brain will stop if you listen to this channels misleading advice about 5 G. 5 G causes brain damage yet the media stopped reporting on it in mid 2020. 5 G caused radiation to go through infants soft spots causing rash disease in New York.
Another incredible video about something I’ve never heard about 👌🏻
Mystery solved! (My 7th grade science teacher demoed this but I couldn't remember the details over the past 35 years, and always been a question in back of my mind. Thanks!
I'm a big fan of cloud chambers. Idk why but it amazes me =)
U r experiments are awesome
Lawrence Hall of Science in Berkeley CA had a cloud chamber exhibit back in the 70's. Maybe they still do :-). It was really cool to watch as a young child. You'd get straight paths, sometimes curved paths, and other stuff. I didn't know what was causing the patterns until much later.

Is there any way to put the air ionization tip coming from below the cloud on an insulated section of base plate so that it would push the fog upwards
This is so fascinating haha loved it keep up the good work 👏
:48 Spread it all around to make it as thin as possible, to both increase the surface area and decrease the thickness. Result, faster evaporation rate.
See this is how we learn how to produce anti-gravity vehicles or vehicles so advance they're alien to us. We need more content like this.
In 1973 professor Lowell Brown took our tiny honors physics class to the cloud chamber at the Univ of Wash. He told he story.... They had discovered the screw on particles. A Chinese professor wanted to name his new particle "the screw off particle", but Lowell had to talk him out of it.
Reverse the polarity of the voltage and lets see if it looks the same.
Doing practical experiment and learning from it is 100 times better than only reading in book. Science is not a theoretical thing but its a practical thing to be understood by practical more easily.liked your experiments.
Crazy how voltage and amps act like a blowdryer in this scenario
We had a science magazine for children (and maybe adventurous adults too) called Jippo back in the 70s and 80s with neat science experiments and mechanical gizmos included with each issue. Have not seen similar thing since then…
Well, actually at the moment of initial start of the electrostatic generator, there is no ion flow just electrons and you can clearly witness the interference pattern on the outer rims of the circle.
So try doing this through a double slit and see what happens.
This video showed up 10 times now I am finally watching 😂😂
Your videos are always very interesting. Hard to imagine how do you come up with do many cool ideas and how do you find the time to build, experiment, record and edit! Blows my mind!
Another episode of not understanding anything but that was really cool
True chad being.
Such an amazing variety of subjects your cover.
Awesome video. Which isotope of Uranium did you use for these experiments?
Whould be nice to have a really slow motion of this effect. Thank you!
Loved it very interesting
5:07 behaves like a pressure wave from a nuclear bomb
Question: That Alpha particle we saw just before ionized the air, is that from anywhere particular or is it just random background radiation?
I'm still learning how radiation works and would love to get a better idea about the sources of background radiation
Question: I know when people get a strong dose of radiation it can kill them slowly but my question is: Can radiation be so strong that it instantly kills or vaporises or otherwise instantly destroy living tissue??
Always loved cloud chambers. One time I spent atleast half an hour staring into one at the Deutsches Museum with my friend lmao
This guy is making my days better than Omegle.
Best science channel of RUclips
love your videos so many creative ideas never a dull moment
Any idea what causes the growing concentric circular rings pattern at say 6:05? What would happen if you just hit the cloud chamber with a very brief burst? Would it grow like that or sort of imprint the initial pattern on the cloud and stop?
Bruh these experiments are so interesting we need to get this guy more views.
Super beautiful and super interesting experiment thank you very much
You should try to do the double slid experiment in this chamber
Great content! You still are coming up with interesting videos! 👍👍
Very small addendum, Beta particles can be either electrons or positrons. Great video, cheers.
Great video!!! Keep it up!
Really enjoyed it. Keep it up 👍🏻
Love your channel! I dont know where to ask this so i’ll request it here. Is lifting your your large neodymium magnet off your garage floor affected by the steel mesh that sits 40-50mm below the surface of the concrete slab?? If so, is it possible to electro-magnetise the mesh somehow and repel the magnet? If so then attach the magnet to a board to make a hover board?
Assuming the steel mesh is there, it's mass is not enough to prevent liifting the neodymium magnet off the floor. And. If present within the concrete, cannot be turned into an electro magnet, so, no hoverboard.
Brilliant, good work.
Action Lab: I'm gonna blast the cloud chamber with electrons. Pulls out a nail.
Me: Goes to the storage to get an old cathode ray tube tv or monitor!!!!!!!
Dude, this is a good one. I guess visible light photons are too low-energy to trigger the phenomenon?
You said it, they are visible light photons, not gamma ray photons.
Tipically around 10 eV are needed to ionise air molecules, so maybe one can try with UV radiation. Consider that visible light has about 1.5-2.5 eV
Wouldn't air ionise all the time if light is that powerful?
@@Francesco_Armillotta 10 ev is the ionization potential needed to ionize super saturated isopropylene alcohol... not air. Air is much higher. For instance most of air is Nitrogen and its ionization potential is like 14 ev. That is why the cloud chamber has to use the alcohol rather than just air.
@@Ddub1083 thanks for the puntualization, nevertheless i was just referring to the order of magnitude. And, yes, the essence is the same: you should use uv light
What would happen if you do a double slit experiment in a cloud chamber?!?
Do the cloud chamber again, but with a magnetic field (preferably big; may need to experiment with the right intensity). This is what they used in the old days to figure out the charge/mass ratio of new particles (of course also have to have an idea of the velocity, including gamma factor if they are relativistic).
0:21 " super easy, barely an inconvenience "
It is really easy, you just need some dry ice and some IPA. If you do not live in the USA, where dry ice is sold at the supermarket, it is nearly impossible to get it. Or very expensive
thnaks man loved it
Circa 1981 Jr High, we used an old glow-in-the-dark watch with Radium dials.
So awesome! Gonna make an ion-nado and watch it swirl.
they use simililar tech with the sr-71 nose tip to break air resistance
Happy onam
We need to film this with an Phantom camera!
one of the coolest stuff ever seen ngl
Is there any way he could do more of this with different samples of radioactive materials?
That would be an awesome Hollywood style special effect
Watching with love from 🇧🇼 Botswana ❤️
Get This Man A High Speed Camera.
Thank you for this
It's really easy (when you have all the stuff). I do enjoy these, thanks! Dave J
Enjoyed it truely .
I have an idea for a discussion or video. Providing an answer to the people that cold is or isn’t real. The common argument is you’re only experiencing the absence of heat.
should explain why we see the alcohol make the little trails. what is happening to actually condense to make the trail?
Hey! I had an idea for a vacuum chamber experiment. So we know that 1 kgs of stones weigh same as 1 kgs of cotton. But due to buoyancy of air ( i know it's neglegible but still) the cotton weight is reduced. So what if we took equal weight of both and then weighed them in the vacuum chamber? Would the weight be same or would the cotton be heavier?
