/diy/ - Do It Yourself

Whats the best way to get a good explosion from an electrolytic capacitor? Reverse polarity with a 12v source wasn't that great with just a slow release of gas from the cap, upping it to 24v sped it up and I got a bit of a pop from one of them but still nothing like the big explosions you see in youtube videos.

Do I need more reverse voltage or is it better to connect them the right way and over volt them? These were 12v car batteries in series and both are in good condition and hold at 12v under load, the capacitors drew about half an amp max.

The capacitors were pulled out of spec low esr types from a SMPS, they all vented from the rubber bung rather than the vent at the top which surprised me.
