{How the noble gases get from the environment into the little bottles}

There's a nice, brief write-up on this subject under "Helium-group gases"
in the Wiley-Interscience Encyclopedia of Chemical Technology.  The 
sound-bite answer is that helium comes from natural-gas wells in certain
parts of the world, and the others come from liquid air (the different
constituents of which liquefy and vaporize at different temperatures).
