This person seems born to educate. Something about the way she speaks, the enthusiasm is infectious! I wish I could of had a teacher like you in high school
I wonder why this amazing presenter is not mentioned somewhere in the credits or in the description. She is Sarah Charley, the US Communications Officer of CERN.
I remember building one of these nearly 50 years ago in my shed, and being utterly amazed. As an amateur geologist I had access to some radioactive minerals which produced a tremendous display, despite not having access to dry ice. I manged to do it with a combination of just ice and salt!
@@DubstepOverdose So long ago, I can't remember exactly. BUt essentially, it was a tray of ice, liberally coated with salt and then covered with a layer of black foam soaked in isopropyl alcohol.
Wonderful experiment! I tried it and it worked for me without any radioactive sources or whatnot that provide more and a wider range of tracks. A few tips for those that are having trouble: dry ice can last for about 24 hours before it sublimates by every 5-10 pounds. Also, the purer the isopropyl alcohol( I used 99.9% off of Amazon), the more and brighter particles you will see. I also found that using a smaller fish tank and observing a more confined space works well. It also help if you use a strong flashlight ( mine was 250 lumens LED) and you point it directly inside the tank instead of leave it standing on the outside. Wonderful video! Thank you for sharing.
Sophie Reeves , This might be a dumb question, but do you have to glue the felt to the tank? It seems like it would just flop to bottom when you turned it over if not.
D Rock 75 I know this is a year late but me and some friends made one and we just used neodymium magnets to keep the felt up. It's also important to make sure the tank to metal interface is free of leaks (like REALLY airtight) otherwise the alcohol won't be supersaturated near the bottom. We used weather stripping and a thick aluminium block to prevent bowing from the cold.
Perfect! Incredible how much you convey in just 4 minutes. Thanks to your video, I just relived the thrill of watching my mother's landlord do something similar for me when I was around 11 years old, in 1954. (Our landlord was Frank Crawford, a Berkeley Rad Lab physicist; he was a natural teacher with a Feynman-like enthusiasm who decided, on a whim, to build me a cloud chamber one day.)
In high school, I was a ’newbie' physics student, I was selected for a visit to tour the Lawrence Livermore Accelerator (Berkeley portion) and the Stanford Linear Accelerator, and much more... changed my life. My dad was a self-taught engineer who worked on many black projects (sr71). Young people, DO, read, listen, meet, visit, ... scientists are all over, many love to mentor, talk yo you if you’re humble, respectful and eager. That’s how I have had many unbelievable life experiences. You too, ok?
Cloud chamber experiments are one of those “aha” moments that really helps solidify intuitively how particles are constantly being emitted. That’s one of the great things about experiments, just learning theory and models doesn’t necessarily build an intuition, experiments do
Great video! I have made my own. I cobbled together several of the old instructions available 25 years ago. My chamber is glass, connected by stained glass foiled joints. Aluminum plate bottom, painted black, check. Thickish art paper around 3 sides for alcohol wicking, white to reflect back light. The light source is a classroom film projector, 300W. Surrounding base is similar with some foam insulation glued in. I think I want to remake it. I want to make a bank of LEDs to replace my awkward projector. I think, I will forego the surrounding white paper. I think a ring of felt near the ceiling (like crown molding?) will provide incoming warm alcohol vapor, without blocking the straight-down viewing perspective. The initial charge of alcohol is plenty, no wicking is really necessary. The viewing session only goes on for an hour or so before the viewers have become saturated with seeing cloud trails. Saturated - that’s cloud chamber humor.
This is a very good quality demonstration. I followed this design as closely as possible, using a cardboard base, an upturned fish tank, black aluminium plate, dry ice, 99.9% isopropyl and masking tape to reduce draughts. It worked like a charm! My biggest issue was the quality of my camera which took very poor videos in the low light conditions. Remember the base needs to be as level as possible and the aluminium should be in contact with the dry ice. Try to get a torch with a narrow beam and manually point it in from the side. I wouldn't recommend LED strips because they create diffuse light which ruins the effect. You need to be able to adjust the position and angle of the light until you're satisfied.
This is amazing, I read about cloud chambers in school but had no idea you could make them with easily accessible materials. I thought you'd need some super high tech setup.
This is fascinating and so easy to construct. She's inspired me to do it. I've assembled all the components except the dry ice and the bin for the dry ice. I'm looking forward to this! I'll let you know how it goes. It would be cool to make a video of it as well.
This is one of the better cloud chamber vidoes I have found, thanks. I would love to try this and put some slightly radioactive materials in and watch. I've seen some welding rods with some heavy metals in them produce a cool little show.
@US LHC Thank you so much for this video! I don't want to re-create this myself, as I am impressively broke, and without much space to do it. ...also your explanations for how the different particles effect the vapor differently... wow. Just amazing. Thank you so much!
Okay, I'm amazed. I'm fifty-six years old so when I was a kid they still sold chemistry sets for children with the good stuff you could easily blow up your house or kill your annoying sister with (I did neither, thankfully), but none of that seemed as cool as this cloud chamber. You are never too old to learn something new.
man I thought these pictures were some crazy instrument, I always wondered how they documented particles smaller than protons/neutrons. I gotta go make this.
Yes! I use to do a very similar activity when i was working in a science centre in the UK. Really great to see other enthusiastic presenters, thanks a million! :)
Well.... this is something new to me. And I've been digging around scientific stuff for a while now. Excellent idea! I'm wondering who came up with it.
i luff her. got me so keen to make my own cloud chamber! i even live near an industrial estate so i should be able to get some dry ice without much hassle
In this version of the experiment, you used isopropyl alcohol. I've read that either water or alcohol can be used. I figure that the compound must be polar so that its molecules are attracted to the ionization trails left by the cosmic rays. Are there any other compounds that can or have been used for this experiment?
I've been doing a research about cloud chambers, and decided to do a school project about it, our teacher accepted it, but I need to show the deflection of particles (alpha particles) in magnetic field. I want to use the alpha emitting Americium 241 (taken from a smoke detector), and set a magnetic device (or just a magnet) around the cloud chamber to make the deflection visible, but how strong must the magnets be, in order to clearly deflect them, will a neodym magnet be sufficient enough? Alpha particles are bare helium nuclei, with two times the electrical charge than the electrons, so I suppose using them should be twice as much efficient than using a beta emitter.
Very cool....d! But seriously, big thanks for a very inspiring video! A question: I know that charged particles deflect in magnetic fields. Could one study this too here, by installing some strong magnets over the cloud?
Well that was very kewl ( No pun intended ) .. Based on your vid of results , the trails in your cloud chamber seem much more interesting than other DYI . I'll assume the reason for that is the extra large volume of the chamber ... Nice. Very Nice ! Thanks .
Notice that the larger more energetic tracks in these vids often appear almost instantly, not as lines, but as straight ribbons, oriented with their flat sides facing sideways. Then, in many cases, the top part of the ‘ribbon’ track travels upward a bit, while the bottom descends. I’m guessing that some of the high energy deposited into the alcohol vapor heats some of it up so that it travels up a bit and then cools off and descends with the lower part, dividing up into turbulent swirls. I've seen this again and again at public observatory exhibits.
What if there is was a house of concrete and led/lead foil, will they still be able to pasS? Is it possible to considerably reduce the cosmic radiation? Did someone measured that?
Just one question thou.. is the cloud trail video taken from the actual cloud chamber built in this video? I tot I saw the horizontal wires that is used in most professional cloud chambers to create a high voltage electric field?
This is really cool. I'm curious what the typical shelf life of a cloud chamber built this way is? For example, how long before I need to replace the alcohol and/or dry ice? Follow up question: Assuming this doesn't last very long, what can I do to make a more permanent one, like the ones I've seen in science museums?
Hi Jim. There are ways to make exhibit-quality cloud chambers that continually run (CERN's S'Cool lab has one) but they are much more expensive. They require a refrigeration unit (to replace the dry ice) and a system to circulate/replenish the alcohol. The kits for these exhibit cloud chambers are ~$10,000 I believe.
So I’m sure these questions come up multiple times but I have to ask if the streaks I have a lance then does it mean that the particles pop in and out of our local space because it’s not going from end to end of the container please help
@@anotherone4669 That's just plain false. The water solution just needs to be super-saturated in the air in the chamber. It's more difficult to do with water because water has a higher heat capacity and vapor point than various alcohols, so you'd need a higher "room" temp and still a very cold or colder condensation surface.
Maybe you will need a phase change cooler to keep the bottom cool instead of using dry ice. And some kind of heatsink up top to keep it at room temperature. It's an engineering proyect for sure. if not a fridge, or an air conditione would require some soldering, maybe a phase change cooler (the ones for computer extreme overclocking) could be a simple way to keep a plate cool. Anyways it will be expensive and kinda loud.
@@ignasanchezl I was reading about a "peltier' device for the bottom and a reversed one for the top. But dont know if they can get cold enough. THese ar the things that cool the plug in picnic coolers with 12v car socket.
I doubt it, they are barely capable of cooling one or two drinks, and you need dry Ice levels here. If not you could just perform this with normal ice.
+Pavla Bednářová Seems to be aluminium (anodized probably) from the sound it made. Any sheet metal should work great, maybe add a coat of black paint to make the trails more visible.
@@randyhavener1851 If you are going to stack them to get a higher temperature differential run one at its rated voltage and the other at roughly half that. The 5 12 volt supplies from an old pc supply are good. Alternatively stack a small one on top of a large one so it can dump its heat into the larger one and get colder.
The "radioactive source" is the universe itself. That's all you need. That's the whole point of this experiment. This gadget is detecting the background radiation - particles - all around us, that is given off by the universe, galaxies, stars, and radioactive elements in the earth itself. All these particles are zipping through us all the time, and we're not even aware of it. The actual particle tracks you can see with this cloud chamber are made by alpha particles (bound protons and neutrons), beta particles (electrons and positrons), muons and cosmic rays (high energy protons and atomic nuclei).
Your base should be dark and it should be metal. You want to transfer the cold to the bottom of the vapor-filled chamber as efficiently as possible. The base needs to extend past the edges of the vapor-filled chamber so the sublimating CO2 doesn't fill the chamber and push out the alcohol vapor.

What is the metal you have used to make the lid ?
Heavy
Lucky if you in US, anywhere else you have to contact chemical companys and buy drice ice in bulk, like 10, 50, 100kg
Was the lid metal or plastic ?
Plastic and dry ice don't work well together. Plastic would get so cold it would crack, even shatter. Definitely has to be metal.
😂😂😂👍🏾 nice ... did u tried scare us with woooohh
Why do the particles seem to appear in a ‘flashing’ pattern, rather than some irregular way?
There's actually so many pattern based on the properties of particles, for example the straight pattern means that's muon
Does anyone know if there's a specific kind of base you can order or is a miscellaneous base enough ?
Your base should be dark and it should be metal. You want to transfer the cold to the bottom of the vapor-filled chamber as efficiently as possible. The base needs to extend past the edges of the vapor-filled chamber so the sublimating CO2 doesn't fill the chamber and push out the alcohol vapor.
"science is coooll"
haha:)
if you don't have dry ice what do you do?
Procure the dry ice from somewhere
So that explains why I get drunk.
