Bananas are radioactive due to potassium 40 which is one very special isotope. It is both a beta emitter, and (very rarely) a positron emitter. When you observed the strange phenomenon around the banana I got giddy with excitement because I thought you might have been so absurdly lucky and observed positron annihilation. Now this is almost certainly not the case, probably just an artifact of dust or something. but I can have my fantasies!

Not only is the content awesome, but the editing is top notch too! Those transitions are super slick, well done

First of all, cool project. One modification I would suggest is to have a magnetic field perpendicular to the surface. Since electrons are negatively charged their tracks would turn clockwise around the magnetic field lines, while alpha particles are positively charged so they would turn counter clockwise. That would be a nice way for you to more easily distinguish between the two particle types. You could perhaps buy neodymium magnets and place between the coolers, just make sure they are pointing in the same direction. I'm not sure where in Sweden you guys are, but in some regions there are naturally occurring radon gas which is radioactive so if you have the cloud chamber in a poorly ventilated basement you might see more activity than if you are in a better ventilated room. You could also test the soil since there might be some trace radioactive isotopes in it from the Chernobyl nuclear disaster. Alternatively test the meat of wild boars, since they like to dig in the ground and eat roots they might be radioactive with isotopes from Chernobyl. After all, it was the Swedish nuclear power plant Forsmark that where first outside the Soviet union to detect the disaster due to the wind blowing from the south east on that faithful day in 1986. Furthermore, there are regions in Sweden with uranium in the ground, so you could consider testing some rocks (I know that there are some uranium ore in Slotsskogen in Gothenburg), however that might be considered illegal mining of uranium so check the laws first. In conclusion you guys have many interesting things you could test with you cloud chamber.

Study and you will get that knowledge.

I used to work in a teaching lab, I always looked forward to the part in the academic year when we got the cloud chambers out. We used CO2 'snow' to achieve the very cold temperatures (it was my job to make it, by jetting CO2 from a big cylinder into a cloth bag!). Seeing actual particle trails was always a wow moment, never got tired of seeing it. The little chambers we used had a built in radioactive source for alpha and beta.

One super easy and cheap way to get something radioactive in Sweden is to go to a second hand store like Erikshjälpen or Myrorna and go to the glassware section. There’s usually some uranium glass there, which is how I started my collection of it. They’re not marked as such though so you have to use a UV flashlight on them to tell if they’re actually uranium, they have a certain glow.

This is hands down the coolest thing you've built, and that's saying something because there's a lot of contenders

Try with TIG Welding Tungsten Electrode 2% Thoriated aka red tip, the thorium is supposed to be radioactive and emits alpha particles. They're not very expensive and you can find them in any welding supplies shop.

This is super amazing, can't wait to see what you put into next.

I have made a TEC cloud chamber in the past and here is something i learnt, if you add an electric field it makes the particle tracks much more defined, around 2-5Kv does the trick. I would recommend buying a bug zapper tennis racket, removing the internal PCB and connecting the negative high voltage terminal to the cold plate and then add a wire mesh above the cold plate that the positive terminal connects to, in mine it was around 100mm above, yours may vary. if you have this on a switch you can turn it on and off and compare the results. another thing that i found was good was to add a few layers of fabric (I used cotton felt) on top of the wire mesh and soak it in isopropyl alcohol, this will last for a long time so you don't have to keep on spraying, you can add a heating element inside of this but i didn't find that necessary. also the Americium found in smoke alarms is a good source of beta radiation if you are carful and want to try it. Another source of radiation is welding rods i don't remember exactly which type

This is pretty cool! You should put some old drinkware or ceramic dishes near the chamber. Some of the really old stuff contains traces of radioactive elements. Or if a family member has an old wrist watch with glow in the dark clock arms.

We made these many years ago at college, and used a large syringe to draw a partial vacuum, this increased the saturation and made a lot more trails visible - you could probably do that by making your chamber a much lower volume and putting a good seal around the base (might need to use glass instead of perspex?), we soaked a small pad in alcohol which allowed us to observe for much longer (place it to one side in the chamber) and cooled the base with a cake of solid CO2 - when you pulled the syringe the chamber went from barely working to amazing visibility, when a gentle pull is kept on the syringe it could be observed for many minutes before the vacuum or alcohol were exhausted - It's good to see it work with peltier coolers, we used to throw them in the bin due to their high power consumption and poor performance on higher powered processors.

Very cool experiment, dude! Congrats!

Awesome project!

Good on you for getting it to work with a single layer of peltiers. It was my experience that a stack of two is needed, a high current peltier cooling the hot side of a lower current peltier, which in turn cools the cold plate. The top layer doesnt contribute all that much heat to the system (with them being driven by considerably lower current than the bottom peltiers) but it greatly enhances the delta-t possible.

Great work! I'm impressed how ChatGPT answered to your question. Maybe it was not clear enough, but you need to connect negative high voltage to that tungsten wire to create electron beam.

It's a -30 cloud chamber and putting a 1626.85C wire (assuming ~1900k hue) is not going to anything other than ruin the effect. Absolutely insane. And how can you connect a negative DC voltage over a wire? Positive and negative in DC just refer to direction of current. If you swapped the connections on each end, you could call it negative, but it makes no difference.

These transitions are top-tier.

I love the effect! If you tweak the voltage of the TECs a bit, you might reach a better input-power-to-deltaT point as the input power and maximum deltaT depend a lot on your setup (cooling, and thermal conductivity of the aluminum plate). Sometimes you have to reduce the power to the TECs to increase the deltaT. Sounds counter-intuitive, but that did the trick for my setup.
