I read in sci.electronics.design that John Muchow wrote (in <firstname.lastname@example.org>) about
'Reducing contact resistance for low volt use?', on Fri, 13 Dec 2002:

Look up 'Wood's metal'. Melts at 80 C, IIRC. There used to be joke
teaspoons that melted in the hot tea. While its resistivity is, no
doubt, quite high, you would only be using a very thin layer indeed.
