While this is not strictly about seismology and I apologize, I thought one of 
the group might be able to help me out with a problem.   Later this summer I 
will be hiking deep into Glacier Nat. Forest (WA) and I will need to suspend 
a communications antenna from a balloon.  I just don't savor the idea of 
lugging a 40 cu ft Helium or Hydrogen tank 20 mi.  I'd hire a heliocopter if 
I had the bucks, but I don't.   I seem to remember that some compound when 
simply mixed w/ H20  would produce huge amounts of hydrogen gas.  I am aware 
of other methods, but they're too risky (acid and alkalis, etc.)  I have 
looked everywhere I can think of and come up dry.  Anyone have an idea??   
Thank You.   Mike.
