Technically, the CRAY-2 is immersed in a bath of Fluroinert(tm), 
an odorless, colorless, tasteless, non-corrosive, etc. viscous
fluid produced by 3M company.  I believe its primary use is as
a liquid base for artificial blood plasma. 

It's damn expensive (~$100/gal).  Several gallons evaporate away every
time the machine opened for repair (due to its low vapor pressure).
