Theoretically, pure water does *not* conduct electricity. It's the other particles (ions, whatever) that allow it to conduct. So, it *should* be safe to run the water over running circuits. Of course, any contaminants (oil, grease, dust, whatever) *could* cause a short-circuit. But, I read somewhere that they did precisely that, long ago. And, that the reason we call the abnormal/strange occurrences in programs, bugs, is that they were often caused by bugs, rodents, etc. shorting out or chewing through the computer's circuits ____________________________________________________________________________________ Sponsored Link Mortgage rates near 39yr lows. $510k for $1,698/mo.
