Why is water dangerous? Well... I'm no expert, but I do know a few people here who are... the chips and components of the computer usually use voltages in the order of 5 volts. Around the circut boards are several lines around 12 volts, and some even higher. Shorting a 12 (or more) volt line onto a pin that's expecting 5 volts will usually cause severe damage... Dumping water (especially tap water from cities...) will short the lines. But if the power is off, there's no voltage anywhere (Or, very little), so damage can't occur. As long as you give the circut enough time to dry, no harm is done. The boards themselves don't mind the water in the slightest. Trust me. I've done it quite a few times. (Note that the water might cause rust, which is another problem...) >We could take this discussion over sci.electronics (which I do read) if anyone >wants to pursue this.
