Wilson Cloud Chamber

[wa5iyx]

Wish that I still had all of the pieces of my Aug 1959 American Basic Science Club kit that made one of these. It used a dab of radium paint on a pin in a suspended cork for the source. I had to get the dry ice from the area "Good Humor" truck. Took 2 hrs to get it working the first time. Used it so often that the odor of ethanol reminds me of it! Sometimes got rid of the excess dry ice by carbonating some water.

thank you so much :-)

[Parmenides111]

Thank you! Very cool!

[sydneydoc]

CERN has just shown that cosmic rays are a major controlling factor in cloud formation ... and hence a major factor in controlling climate (contrary to the claims of the IPCC)

It's a pity that more people haven't had the experience of playing with a Wilson cloud chamber.

[X0verXDriveX]

I'm sorry but that's REALLY interesting!

[Nilguiri]

"Most YouTube users wouldn't find this very interesting"? What an idiot.

[motaile]

@Nilguiri perfectly understandable comment on his part. Most you tube users are idiots that watch things like lonely girl and box man

[dakaha1]

. Hi could you please tell me how to build a cloud chamber as yours?

[Invadurr]

I found this VERY interesting :D Well done!

[The83rdTrombonist]

Just the idea that positrons are meeting electrons and the reaction can be seen visibly to the naked eye is amazing.

[xnoobxinstinct]

This is awesome.

[LK7Migue]

Man that is motherfucking awesome!!

[Branflakes91093]

0:34 "Yeah, but most Youtube users probably wouldn't find this very interesting"

WRONG!

[Flachzange1337]

Apply high voltage. Then the tracks will be more clear and sharper then they are at the moement.

[miloxfromchile]

don't u have ever considered the possibility of getting cancer with that thing?

[mtber666]

VERY unlikely to the point it's almost not worth considering. Unless you ingest it, or say stick in your pocket for a while, it's negligible.

[racastilho]

This is really great, but I have question: these particles are moving almost at the speed of light, right? Or at least, ridiculously fast... So, how come we have this so clear impression that partciles are shooting from the source, and not towards it?

[BraedonR]

Nowhere near the speed of light, but very fast all the same. What happens is, as a charged particle passes through the vapor of Ethanol they ionize it; the resulting ions act as condensation sites, and a mist forms. Its kind of like the trails of water vapor a jet makes. So the places the particle visits first are where the vapor apears first - the mist follows the particle in other words

[racastilho]

Thanks for your your reply BraedonR! Still, I would expect to see a line appear all at the same time, without the giving away the direction in which the particle is travelling (unless we watch it in slow motion).

[Pimpmastahanhduece]

hmm, i think i know what you mean. i think its like a sonic boom. the plane is going faster than the sound waves, but the vapor trail is thicker the farther back behind the plane so its not that your seeing the particle moving slow enough to see actually moving, i think its vector gives an impression of a wave of cloud condensation which obviously moves slower than the thing that caused it. smart observation though.

[Pimpmastahanhduece]

because you can 1)block the path and see if its inside stopping at the barrier or outside the barrier, and 2) transfer of energy causes whatever it knocks into away also.

these are fermions, your thinking of transfer particles and bosons.

[mentld]

racastilho: the particles collide with the alcohol vapor which slows them down.

hope you get what i meant to say, english isnt my first language

[rluna727]

great video

[vladkeren44]

I was interested.

[Timotheedle]

nice, this is good for doing homework when you're absent the day of the lab. thanks rmvvwls

[HeliosTG]

This is boss.

[bobfrank666]

like a boss?

[man4hire]

Very cool! I thought the radiation would be ejected quicker, but oh well.

[muffinpeople11]

:) wow...amazing what technology and studies can create!!! Who would have known? Great job. I find science and every little cell around us amazing.

[th3d3wd3r]

Haha you see, it's both very interesting and very beautiful too.

[sunesissociety]

oh my goodness! What if one of those particles was really big, like the size of a volkwagon or a tree? ((shudder))

[rmvvwls]

Well, the video wouldn't be on here, for a start. :)

[egdirtlap]

NOw You can put it on youtube: I KNOW THAT PERSON!!!!!!!! WOOOOOOOOOO!!!!!!!!!!!!

[rmvvwls]

Who are you? Wait, Jack Paltridge?

[Kalywonkas]

@sunesissociety that's what a jetstream is :) exact same thing as this.

[DrillianSora]

Very interesting. And very cool.

[MAPSTEW]

hey, i was in a band called "the wilson cloud chamber" in the 80's !! respect to jim, paul, dav and yours truly, stew!!! and yes , one of us did actually build one, tho not me!! we was a cool band tho, limerick, ireland.

[marmaladekamikaze]

Irish bands are the best...nice cloud chamber too.

[moeburn]

that is an awesome band name. I too am Irish, and that sound's like something my family would invent.

[TTUchem1010]

Thanks! :)

[G3n3r4lf3ldm4rsch4ll]

Woah!! Very nice work!!! Have you calculated the energy of the alpha particle with the distance between the uranite and the point when you can't see the particle's path?

Thank you for sharing this video!

[waterboardingfan]

Now I want to make one of my own!

[rmvvwls]

It's well worth the effort

[taliban0king]

"well you tube users wouldnt find this interesting..." wWELL I DO! so tell that guy...umm...whats his name THAT I DOOOOOO! that is all

[rmvvwls]

Consider him told

[KindlyWise]

I particularly liked the line that broke off at 90 degrees to itself...does that mean it decayed into yet another pair of particles?

[rmvvwls]

Not likely. We believe that it simply hit another particle and ricocheted off at right angles.

[bionerd23]

its sooo beautiful! *gazes in amazement*

now i know what i need to assemble next. ;-)

[porklodgemaddness]

I find this very interesting.

[jonnda]

as do i.

[gammaparticles]

How does one come across uranite on the market

[rmvvwls]

call Lucas Heights and ask them can you have some

[michael2B]

wow! What's in the beaker (rad source?)
