- In this video I show you how to make the world's easiest homemade cloud chamber to detect radiation particles. This is so simple to do but the results are so amazing! You can actually see the path that the radiation particles take through the cloud chamber! It is made by using a supersaturated vapor of rubbing alcohol. When a radiation particle strikes the vapor it ionizes and forms a nucleation point for the vapor and you see a small cloud where the particle went.

Hi everyone, so I messed up in the video I said 15 km/s and I meant 15,000 km/s for 5% the speed of light. Whoops:)
K
It's soooo cool!!!! Please keep uploading more videos!!!
The Action Lab hey why don't u start making videos like crushing things in that iron thingy like 1000 TISSUE PAPER vs the crusher
The Action Lab Can you try and rust Iron with fire? I know the burning is just rusting in a different way because it’s oxidation. Can you try this my boi?
The Action Lab Question! How much radiation does phones and laptops give off and having them next to you all the time can actually affect your body?
Now put a radioactive thing near it to see a lot of lines
Try putting a fire detector near it, I recall it radiating Beta-radiation, could be Alpha though.
If I remember this correctly, they detect smoke by constantly locking for it's own emission of radiation along a short path. When smoke (or other fumes) enters the detector however, it cuts the flow of beta-rays and the signal is broken. That's when the micro-controller can be sure there's smoke of some sort.
Put a smoke detector near this and you’ll probably see the americium
naah, if you want to see the americium you just have to open the detector and look at it. The electrons emitted from americium however..
Gustav Ferdman I remember it's alpha particles not electrons
en.wikipedia.org/wiki/Smoke_detector
Seems like it's a small amount of gamma as well. But no beta, you're right about that Rick.
I have learned more physics and chemistry from your videos, than my textbook! 🙏
tutorial master!!! Me to !!!
me too ✋✋✋🖐🖐🖐
No comma necessary
@mfpears hahah cheers mate! That comment was made 6 years back, i was probably learning physics, chemistry, and math with no time to learn english grammar. However, i cleared IELTS with an 8 band result out of 9 in 2022 and now very well settled in England 😂
I love how jammed pack with info your videos are
Andy agree
He is used to be very efficient person and uses all the characters of the description.
_Very good TH-cam Citizen_
Why schools don't show us this ?
Pro Player 1⃣ Do u still play tanki??
Pro Player 1⃣ because you need to learn gramar first xD

The irony.
Pro Player 1⃣ yes why :(
Bring it to Chernobyl or have someone bring it there and get it on video.
Why go all the way to Cher Chernobyl. .... fuck-a-shima has blessed the west coast USA with plenty of radiation. Just go out to your back yard or your kids playground. Hell, the milk in your family fridge should work too!
Lovely.
Shakes head...... as I scratch this curious red rash forming on my arm.....
You don't need to go to Chernobyl to show radiation especially now that after all this time the radiation level has decreased a lot. There is many things that are radioactive that you can use to test it for example radium watches or uranium glass/potery as well as any radioactive ore
Karvast Americium from a smoke detector would be perfect!
Chernobyl's background radiation in legal areas is almost indistinguishable. A much more interesting idea is to put a radioactive sample inside the cloud chamber.
@@Gregorydaerr1971 Okay Gregory, vey cool!
This is amazing! This is how teaching should be, I am generally interested and actually seeing it in such a simple way makes such a complicated concept almost tangible. Thank you.
Lately your videos are so awesome. Packed with amazing information I have never heard of.
This is really an awesome DIY cosmic chamber. You have not only showed us how to build it but also guided us how and where look and giw do they look which is really awesome 🙏
Holy snap, this is so cool. You're a genius, I've learned so much from your channel.
Best science channel on the internet! I’m definitely gonna try this experiment on my own
That is freaking nuts! Another great video.
What if you put banana or a magnet inside? Banana should emit particles, magnet should bend them
Interesting. I do wonder how a magnetic field would affect them.
I second this idea! Follow up video with banana please!
Magnetic fields will bend the alpha and beta particles. Beta particles are just high speed electrons and have a negative charge so if your magnetic field is anything but parallel to the direction it’s travelling it will experience a force that will bend it. Alpha particles are essentially helium nuclei and have a positive charge, double that of the beta particles due to it having two protons. These will bend in the opposite direction in the same magnetic field and are much heavier particles so they won’t bend as noticeably :)
@@pagey1529 they're very fast so a small mag field wouldn't do much, can't say the same for a planet or a star
That is kinda how they found the first anti matter the positron

Its not because of this but aigjt
This is the best video you have done yet. I am bunking work tomorrow to do this experiment.
This is the coolest science video I have seen on TH-cam!
certainly the most awesome video yet on your channel !
That was one of your best videos. Bravo.
This is such an informative video, even all the little things you mention are super interesting and helpful!
Absolutely fascinating!
Fascinating!!
That was so cool!
Ok, that was REALLY cool!
This is hands down the best thing I have EVER SEEN! In terms to science that is. Can't come before meeting my babies for the first time. Lol.
Super cool!
Amazing, I legit love these videos
Liked before watching! Nice video 👍

Thats awesome
Omg!! That’s so awesome!!! 😱😱😱😱
thank you is very nice and work :)
Nice👍
So good
Nice!
That's pretty amazing if u think about it, like u can detect these particles by making a simple stuff like that ._. Wow! Thanks for the amazing vid man. Keep it up, keep enlightening me with your knowledge :'D, btw I'm doing my A'levels in Science and your videos are motivating man
Put the radiation source from an ionizing type smoke detector in the cloud chamber. It's usually Americium. That should light up that chamber really good
Amazing
You are my science teacher
If I weren't already a subscriber, this video would make me subscribe.
It is amazing we don’t have more incidence of cancer. Just think about the complex processes the human body must do to prevent it
The process is called angiogenesis. It's been shown that virtually all instances of cancer also correlate with an abnormally high angiogenesis level. Angiogenesis is just the process your body uses to create new blood vessels. In a normal person, this level stays healthy and the body does not create new vessels to feed the cancer's growth. In unhealthy people, the body uses angiogenesis to grow new vessels to start feeding the cancer. This is why people with obesity are more likely to have cancerous growths. Their body's angiogeneis level is already abnormally high because it has to grow new vessels to keep the excess adipose tissue (fat) alive.
Angiogenesis is just a tiny part of the story, and only happens after the tumor has already been formed. There are many other reasons why we don't constantly have cancer:
1. We have protective measures against radiation, the outer layer of our skin is dead and has pigment proteins which absorb some of the radiation before it gets inside.
2. The vast majority of these particles will not ionise DNA, they will probably ionise water molecules instead. This probably accounts for nearly all of the 15,000 particles per second.
3. The vast majority of damaged DNA is repaired. The body has many methods for DNA repair, the least effective of which is non-homologous end joining, which still has a success rate of over 99.9%. This repairs the rarest form of DNA damage, and other forms of DNA repair are even more accurate.
4. The vast majority of the DNA mutations will be in non-genic regions of the DNA and have minimal to no effect on biology. They could also be in genes not used by the particular cell type that was mutated.
5. If something is altered. The cell has a number of check points that it can go through to check for errors. Too much mismatched DNA - which is caused by this type of mutation, will set off alarms and cause the cell to kill it self. So will a bunch of other things, like if a protein is over expressed. This is what happens when you get a sun burn, your cells commit mass suicide due to DNA damage - which makes sunburns a little scary.
6. Even if your mutation is in a an important gene and it makes it through DNA repair, and evades detection during a cell cycle check point, most mutations will not cause cancer. Many might even kill the mutated cell. Only certain genes will cause cells to become cancerous. Often these are the genes that are involved in the aforementioned checkpoint/suicide process, or genes that encourage growth.
7. Unhealthy mutated cells, and cells on their way to becoming cancerous will stick out from their surrounding tissues. They often present weird proteins on their surface, which usually draw the attention of the immune system. Most of these cells are killed before they can become cancer.
8… Once a cancer has grown for a while it will start accumulating mutations that allow it to bypass check points, encourage growth, and evade the immune system. This makes the cells more vulnerable to mutation, allowing them to evolve more rapidly. Eventually the tumor might become angiogenic, and/or metastasise.
Long Story short - Many, many things have to go wrong to give us cancer. Either the systems that prevent it break down (eg. ageing), or we have to challenge them constantly and dramatically (eg. smoking, tanning, nuclear fallout, mutagenic chemicals etc.). Also the sheer number of cells in the human body increases the chance of something eventually going wrong.
Angiogenesis does not only happen after a tumor has formed... it happens constantly. If you cut yourself, your body creates new vessels as your skin heals for example. It's been found that most healthy men and women have multiple tumors in their body that the body simply is not feeding, so they do not grow into cancers. I'd say angiogenesis is a key factor in controlling cancer and not just a tiny part.
Well, life developed in our slightly radioactive environment, so its accustomed to the normal background radiation amount
Dna has self repairing mechanisms that are in effect all the time. Just google Dna repair.
very cool
So cool
Forget the invention of sliced bread, this is astounding!!!
I am a grade 8 student, and we are learning about radiation right now in school, u should explain more about this thx.
This is sweet. Your content is amazing. How do you know so much magic?
Alpha particles surely can't penetrate that plastic cup, and beta particles most probably can't penetrate that cup. The only particles you get there seem to be background gamma, which is consistent with their rate. Very cool video! Thanks :)
Does it have to be Dry Ice? how about regular ice?
Yes, the temperature needs to be below -26°C(-15°F) but normal ice can only reach 0°C(32°F) which is insufficient
Good movie I loved it HEART ♥ OF A MAN!! THE SHACK
Nice video! Is it possible to make a version using Peltier elements instead of dry ice, or is the minimum temperature required below what a Peltier element can reach? Would be nice to build one (perhaps bigger version) that can run permanently!
Next video about radiation, that would be an interesting topic!!
Try using space bags or vacuum seal bags with your vacuum pump. I think it will look cool.
Have you considered using Vantablack (or a similar light-absorbing paint) in the background, to achieve greater contrast between fog and particles?
I want one‼️
I need to make one of these…I have a uraninite and pascoite specimen in my collection, kinda want to see what the output looks like visually.
This is awesome.. Can't wait to try it out on some bannanas
I think its amazing that we experience time at a rate that we can witness these particles interact. What are the chances?
Nice
Disappointed to see lower views and comments on such a great video
could you do this on a bigger scale? Very interesting.
Cool..👽
HOW ?? incredible ........... explain it in detail
Knowing the high speed of the particles, why do we see the line forming from one side to another, and do not get an instantaneous line of condensation ?
He made even before anyone knew this was possible 😂🙌
That was NEATO
awesome
Would be interesting to see how it reacts to x-rays.
WoW!
Can you watch the path with a slow motion camera and see the streak slowly form
I find this all _incredibly_ ionic.
Ionic. I got it. ......Ironic- ionic.....tomato- potato.
Would like to see the result when you bring sth light or even strong r-active stuff to there.
oh wow , that was so cool l can't believe you are so smart lol l love it!
pretty cool that someone who graduated from school long ago finds information like this still interesting even though its of very little use at your age.
What happens if you partially shield it with some lead? Are you able to only see the particles in one direction from the opening?
Interesting video, thank you for that ! :)
But as a student studying for high energy physics i have to say some things :)
Photons are neutral charged, so they cant be registered by that camera cause they dont cause condensation.
And there a small part of alpha particles from Radon. The most part of that you seeing is electrons and muons. Muons are cosmic radiation which passes the atmosphere. So there a lot of this things.
cheer for science, guys
nice correction homie (слава Україні); can you please point out which evens are muons and which are electrons in this vid? (well some of them/a couple at least?) can you timestamp a few clear muons?
+Bohdan Dudar well photons are neutral but they are the carrier of the electromagnetic force so they can definitely knock electrons off and ionize, but they are not likely to hit any molecules in the gas chamber, but they can hit the walls and cause beta emission from the walls I believe. I didn't mention muons, but you are right they are present but since their lifetime is so short I left them out. Good info though! Thanks for your comment:)
Can you use this method to measure radioactive particles in liquid? also, what is the detection limit? cheers :)
my question is can you make a huge home made particle detector with a clear bucket so you can see more particles at once?
This is one of the coolest things I’ve ever seen. I hate to nitpick but is 15 km/sec really 5% of the speed of light? I thought it would be much less than that.
I just saw your correction comment. My bad
If you brought this to Chernobyl would it go crazy?
Kieran DeLacy Very crazy😂😂😂
DEAD LOCK waayyyyy crazier than crazy
Ameer Albadri Craaaaaaaazzziieerrrrr
Kieran DeLacy Nope it would not get that crazy
HI there! Just tried replicating this experiment, except with 70% isopropyl alcohol and I didn't get results similar to yours. So, I guess I am challenging your methods here; were you using any equipment (high-speed camera, etc?), captured long periods, etc, to capture these moments? I also permanently sealed the environment with strong glue. My thoughts are that 70% should have a high enough concentration of isopropyl alcohol. Also, even though my cup had signs of condensation, due to the 30% concentration of water, that was frozen around the perimeter and appeared outside of the cup. There is an uncertainty that the space between plastic molecules is not big enough to let the majority of these particles through OR that we aren't hit with as much "cosmic background radiation", likely because most elements we're surrounded by having long half-lives. It could additionally have something to do with the probability to 'hit' a particle at just the right moment. But, because of these uncertainties, I cannot validate or replicate the results here in the video :(
I even placed a small piece of dry ice inside the cup to attempt a better visual, as I figured these particles would not have trouble hitting the alcohol concentration and effecting the CO2 gas like we see here with the "stream-path(s)" the particles in the video made. However, I wasn't able to confirm that the only possible stream was due to an ejection (i.e. radiation).
Your input here is appreciated as I would LOVE to see the possibility with my own eyes. I even wanted to show this to my significant other, who was also with me at the time of replicating the experiment. Lastly, any research articles you may have would be extremely appreciated! Drop those in a reply if you can, please!
I can't believe no one has replied to you. Try doing the experiment with 99% alcohol again with a big chunk of dry ice under the cup.
wow, a beautifully written comment, but nobody looked at it, in my opinion, make sure to have a tight seal, use heatsink modules instead of dry ice, use very high concentrated alcohol, use a good camera and a good light source
Had a similar problem with 91% alchohol. Maybe it just has to be super high concentration?? Idk
I think the dry ice if inside the cup would significantly dilute the alcohol. And perhaps use close to 100% alcohol.
Cool
the so cool channel. now use a magnet to trap a particle
Is this work the same way in Vaccum? Please make a video on it too.
