A thin sheet of paper stops alpha particles, that's why the detector didn't show any extra particles. Plexiglass will stop beta particles and the K40 in bananas is a beta emitter. It's mostly gamma rays you see. If you want to be sure if it's alpha, beta, or gamma place the chamber in a magnetic field. Alpha and beta particles will be bend into circular paths while gamma rays stays unaffected.

Hey ! To everyone trying to replicate this setup, i found something interesting, it seems that you can go wayyy under 2-3° with some fan and heatsink. I found out that the major problem is the thermal coumpound you apply. With standard electronic one (the white one, 1W/(m.K)) you can't go under 2-3°C. Out of curiosity, i tested a good one (for computer CPU, 8.5W/(m.K)) and... -13°C. Same heatsink, same fan. It seems that a "bad" coumpound is not enough to draw the heat from the module to the heatsink, and you thermal balance in the module is at a way higher temperature.

[@hurmzz]

Wouldn’t cooled water with salt also work better then ice? Ice will simply melt around the heatsink, locally raising temperature quicker. *edit: didn’t watch end of video yet, expected better results with salt

Pro tip (3 years later, I know 😅): Alpha radiation can be stopped with a sheet of paper or even our dead skin cells. So putting the bananas behind that plexiglass is probably the reason it didn't work at all. Try putting them inside, It should work better, same with the smoke detector, which, btw, could be an optical detector with no radiation since they kinda "banned" ionizing ones

[@markwhitaker3017]

I was going to say the same thing, lol

[@cyclingbob1]

Better pro tip 😉 … The radioisotope in bananas is Potassium 40 which decays (mostly) via beta particle emission. NO alpha particle emission. These particular beta particles have more than enough energy to get through that plexiglass. But, given the half life of K-40 (over a billion years) and it’s puny specific activity, you’d have to leave one there for a while to spot any ionisation. They just get missed in all the other natural radioactive stuff 👍🏻 Yeah. I’m fun at parties.

10:22 To anyone trying to replicate this (and to @electroboom himself, although I don't think he'll see this by now): alpha particles are blocked easily by basically anything denser than air and without actual radioactive stuff, you are not likely to see any other type of high energy particles comming out of it (maybe you are lucky to have a few radioactive isotopes on your bananas), so you have to place them inside the chamber so those alpha particles are made visible. And with the smoke dectector... Well, some of those do have a tiny piece of radioactive americium inside but a) not all of them use them and b) it will still mostly emit alpha particles so you still need to have it insed the chamber to properly see stuff coming out of it... And probably destroy the sensor to expose the americium block inside anyways haha. I LOVE cloud chambers and i will definitely make my own some dayand @electroboom actually made some great job shoeing how to do it. I syill think dry ice is still easier though...

Thanks for the innovative video. The plexiglass housing is blocking most of the alpha particles from the 241Am source (smoke detector). It also emits low energy gamma rays though which you see when you put the source outside. You would be able to detect only gamma rays or particles that can penetrate through the case.

[@dylansawyer3446]

Gamma rays can not leave a visible track inside of a cloud chamber as high energy photons do not really interact with matter the way that other particles do even tho they are ionizing radiation. What you are observing is a particle called a muon. Atmospheric muons are produced in earths upper atmosphere as a result of the decay of pions (a charged meson with approximately 270 times the mass of an electron) muons as well as muon neutrinos are both a product of pion decay. Pions tend to decay in about 8.5x10^-17 seconds. Pions are generated in the upper atmosphere when a proton collides with a molecule.

I am no engineer(electrical or mechanical) but I am a HVAC Technician. I thought of a improvement on the design for lower temps. Air over heatsinks are no good air has a low heat capacity. My idea would use a small refrigeration circuit to chill a bath of isopropyl alcohol and have the heatsink submerged in the actively cooled alcohol bath. As the alcohol condenses the sub zero plate will be pitched so it will run off directly in to the bath the heatsink is sitting in. Maybe a mini pump and a float switch to recirculate the alcohol to the top of the device to be evaporated again. For the lighting using a laser that projects a flat wide beam would be perfect for this application because no laser light would hit the metal plate as the beam would be parallel to it.

10:33 as someone who has smashed many many smoke detectors to get the americium from them you’re going to need to remove the source, it’s going to be in a little plastic container mounted to the main circuit board of the smoke detector. You need to rip that open and there should be a small star shaped bit of material. It is safe to handle and only emits about 1-6 uCi. Americium is primarily an alpha emitter although it’s pro generate radioisotopes can emit differently. Alpha particles only travel a few centimeters in air and have a very difficult time penetrating materials. This is why they are used in smoke detectors where the source is placed in-front of a detector. If something gets in between the source and the detector (like smoke) the alpha particles will stop reaching the detector and the alarm will be tripped. Due to this property of alpha particles the source will need to be placed inside of the box. You can identify paths made by alpha particles fairly easily. They are fat little dots. Don’t eat the source and don’t loose it and don’t touch the little star bit.

It's ok, we were just hearing the voices in Mehdi's head.

[@Ciaran55]

I really love the fact that Mehdi’s “My Life of Failures” book also features a failure: he misspelled his channel name 😆 (10:51)

[@mopsbackupaccount5128]

I too only make failures.

[@anirbanbhattacharyya0070]

there are no failures - Master Accident

6:18 it’s been a while I’ve seen the back of a freezer.

[@davec.6456]

I made a cloud chamber from a kit my dad bought me from Edmond Scientific Catalog way back in the early 1970s. It came with a little bag of uranium ore and some radium! I lost the radium, but I still have the uranium ore. I read someplace that alpha particles (or was it beta?) turn aluminum atoms into silicon so I placed a piece of aluminum foil in with the ore, which I kept in a baby food jar. It’s been in there for about 50 years now. I wonder if anything has happened.

[@OkOtChA]

I lost it when he said Slap XD
