Clips of the particle decays caused by high energy radiation that comes from space and passes through us all the time!
Come see our cosmic ray detector! Learn about cosmic rays and much much more at the STAR Symposium!

Looks like good prevention for many cancers would be lead underwear.

wow @ 0:37 :))

@ebdavidson1 Ok, thanks.
I love these could chambers, but it's too bad that you can't really have one as a desktop attraction. I was thinking it would be nice of I could take a peltier module and make a cloud chamber that I wouldn't have to cool with liquid nitrogen or dry ice. I don't really mind if I have to plug it into an outlet.
A compressor would be kind of loud...

@yellowmetalcyborg I'm not sure that the efficiency would be high enough. You would certainly need a lot of power. It would probably be cheaper to use a compressor and coolant. Cheapest and simplest of all - dry ice.
Another cheap idea, if you have the means to handle it, would be to use liquid nitrogen, although you need a convenient source and it wouldn't last very long in the tray unless it was well-insulated.

@ebdavidson1 Do you think that peltier cooling of the bottom would work just as well as dry ice?
-
There is an interesting theory that the Great Pyramids of Egypt and Mexico were built as they were to be cosmic ray shelters. Apparently underneath enough concrete or earth the rays decrease.

So freaking cool!

its so awesome to think we are being hit by these wether we like it or not lol. i find it even more interesting when going sub atomic to the subatomic particles where the neutrinos are like hitting everything millions of times a second and still barely have a nudge on sensory devices because they are barely interfer with anything. tesla said he was harnessing this particle, he called it a "slightly negative neutron", and surprisingly these particles fall into this in one form or another!

You need like 97%, and a high temperature gradient. We got the best results using dry ice at the bottom and just warming the top with our hands.

well, you definitely can use peltier coolers, as google will tell you. You need a rather large heatsink, however, and it is not as nice as it is with dry ice
