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 TH-camr

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 TH-cam. 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 TH-cam 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 ..
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.
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.
@@WatFat lmao
With a smile on his face
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.
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.
The cloud chamber is my all-time favorite experiment ever because it’s so simple and so incredible.
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!!!
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 😉
@@thehyperscientist1961 *M Y_ C O M M E N T_ G E T T I N G_ D E L E A T E D_ P R O V E S_ M Y_ P O I N T!!!!!!!!!* 😡😡😡😡😡😡😡😡 PEOPLE SELL OUT TO THE 5 G NARRATIVE AND ARE PAID TO LIE TO US ABOUT THE UNTESTED SURVELENCE SYSTEM!
@@insectbite1714 Deleted? I still see your comment here
James actually made a video regarding this issue: th-cam.com/video/nKPw-dnxZTo/w-d-xo.html
We're blessed with another masterpiece by James. So when do you collab with The Slow Mo Guys?
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.
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)
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.
this is by far and away the best video ive seen on your channel. more practical particle stuff !
Wow that was really good work! Could have watched that for ages.
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 :th-cam.com/video/snSIRJ2brEk/w-d-xo.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.
Your channel is so interesting to watch. Keep up the good work.
Wow thanks man!
I commented on your last video asking for this cloud video!
VERY informative. So happy and grateful that you make these videos! I’m learning so much.
Best video yet. I had no idea cloud chambers were so easy to make!
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.
I wish my school have such teachers
Who has such good luck ?
Very good. Most videos seem to assume you know what a cloud chamber is - and I do, but I want to SEND IT TO PEOPLE who aren't nuclear physics nerds. So thank you for explaining exactly why it works! Then the party trick at the end was awesome... All the more reason to build one at home tbh!
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
Experiments after experiments, it only gets better. Amazing channel
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.
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.
I like how you used the sponsor product and recommend it later. Definitely makes it more trustworthy
So awesome! Gonna make an ion-nado and watch it swirl.
This is so fascinating haha loved it keep up the good work 👏
Bruh these experiments are so interesting we need to get this guy more views.
Absolutely astonishing. Bravo 👏🏻
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!!!!!!!
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
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 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
Another incredible video about something I’ve never heard about 👌🏻
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.
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!
Nice one. Well done getting a sponsor. About time tbh. Good luck for the future.
U r experiments are awesome
VIDEO IDEA: Can a tiny object break the sound barrier easier than a big object such as a jet?
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…
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 think these are called diffusion chambers, cloud chambers have a sudden volume expansion mechanism which creates supersaturated vapor then condenses areound the nucleation sites.
Great content! You still are coming up with interesting videos! 👍👍
Does that blast from the nail cause thrust? Could that be used in the vacuum of space?
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!
Really enjoyed it. Keep it up 👍🏻
Awesome video. Which isotope of Uranium did you use for these experiments?
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.
That was your best video ever. Loved it!
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.
-Matt
Such an amazing variety of subjects your cover.
Wow, this is so cool! Thanks for sharing!
Best science channel of TH-cam
What would happen if you do a double slit experiment in a cloud chamber?!?
I'm a big fan of cloud chambers. Idk why but it amazes me =)
: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.
Nice expriment , will you get a spiral trajectory if you put that cloud chamber in a magnetic field.
Super beautiful and super interesting experiment thank you very much
love your videos so many creative ideas never a dull moment
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
So that's how they control the weather..
Exactly! You can easily tell when the destructive 5 G companies paid this channel to praise cancer causing 5 G and HAARP. And yes I have seen plane drop liquid before then afterwards there was a storm and the water from the storm tasted like radiation!!!!! (this happened in a 5 G area and 5 G helps them control the weather)
Great video!!! Keep it up!
i am truly impressed from this science experiment
Watching with love from 🇧🇼 Botswana ❤️
This video showed up 10 times now I am finally watching 😂😂
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.
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.
Hello, can you please guide me through the process of make electron gun? How can I make such devise to gun electron?
Old tvs have a cathode ray gun that fired electrons at phosphorus-coated glass.
Whould be nice to have a really slow motion of this effect. Thank you!
That one person doing this with a cut on their hand: AAAAAAAAAAA
Brilliant, good work.
Man I remember when I first found this channel, you were doing hot knife videos and using your hydronic press to crush stuff, now you just blow our minds every day, love it!!!!
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
Hey man , awesome video as always ..big fan .👍
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).
one of the coolest stuff ever seen ngl
You should try to do the double slid experiment in this chamber
This guy is making my days better than Omegle.
I love science and you help me to learn about it more. Thanks very much. From India🇮🇳
thnaks man loved it
We need more of these experiments showing different radiations
No, he is paid by 5 G companies to praise cancer causing 5 G. His EMF counter is rigged just like Chinas smog counters are.
Always loved cloud chambers. One time I spent atleast half an hour staring into one at the Deutsches Museum with my friend lmao
Loved it very interesting
Enjoyed it truely .
That would be an awesome Hollywood style special effect
I'd love to see a CRT electron gun fired into a cloud chamber. Would it form any sort of picture, or pattern?
Reverse the polarity of the voltage and lets see if it looks the same.
Crazy how voltage and amps act like a blowdryer in this scenario
Very small addendum, Beta particles can be either electrons or positrons. Great video, cheers.
Thank you for this
What happens if you put a CRT electron gun in front of the chamber?
This Channel Is Awesome! 😎👏
should explain why we see the alcohol make the little trails. what is happening to actually condense to make the trail?
We need to film this with an Phantom camera!
@The Action Lab Was that with no radioactive source in the chamber? Was that just back round radiation or did you have something near the chamber?
What about the wave-particle duality? Are we seeing electrons (Beta-particles) passing through the vapor as particles because they are interacting with the vapor?
