I would rather someone tell me instead of trying it out myself. |

The oxide insulator on one of the foils erodes, causing the capacitor to become conductive. It becomes a short circuit, conducts a metric assload of current, and gets hot. Then the electrolyte fluid boils, building pressure, and it pops. Try it yourself with one that has a safety vent. Why? Because big bangs are fun. >:D But don't do it with a cheapo non-vented one or you could put your eye out.... Dude... get your email address out of your signature, that'll be sniffed up faster than you can say "spam"... |

I connected a small electrolytic cap backwards once. It was unvented. When it blew it scared the crap out of me. I'm always cautious now when wiring something up to the point where I close my eyes and grimace the first time I apply power to a circuit, just in case. :) |

I'm suprised no one has posted this yet... :) (among all of the other videos on youtube of capacitors exploding) |
