I hurt my keyboard......

[Dazed_75]

Exactly why I said "basicly not conductive".  In other words it is a crappy
enough conductor to not worry about in most situations.  Certainly there are
better insulators, but as liguids go distilled water is pretty safe until
impurities are added (such as by rinsing stuff).  So rinse thoroughly and
maybe even repeatedly (with fresh clean water) for some situations.

Almost anything will conduct electricity under some circumstances.  One of
the other labs where I used to work (Central Research Laboratories at 3M)
spent a LOT of time testing materials under different conditions.  What
qualifies as an adequate conductor or insulator really does depend on your
usage and point of view.
