Hi,
I'm attempting to make a condensation cloud chamber to display alpha and beta particle tracks to a class of school kids as part of my placement.
I get how it all works but I'm having real trouble with two things...
1) Finding a source of high purity alcohol.
2) Getting hold of some dry ice.
My questions are:
Will using methylated spirits work instead of the recommended propanol and will liquid nitrogen serve as an acceptable replacement to dry ice. I know its cold enough but am worried it might be too cold.
Cheers.
