The last time I blew something up was a Bogen DB130 Mono Hi Fi Amp I had in the 60's. As a kid I used to find old TV speakers and hook them up to my amp, turn the volume control to max and watch the voice coils smoke. I did this many times without damaging the amp. That is until the last time I did it.The Amp started smoking, almost caught fire, and then just died. Needless to say, I was a kid with issues. LOL!!

Maybe still with issues, LOL.

I blew/killed a Muse cap.

You might be right!

The biggest electrical explosion I have been lucky enough to be present for was when I worked on an engineering team in college that built hybrid electric vehicles (back in the late 90's).

Anyhow we had a 3phase induction motor rated for about 115kW. The controller for the motor used 3 LARGE IGBTs. Each transistor was ~3inches wide, 6 inches long and 1.5inches high, with the "leads" on top (actually lug bolts is a better term). Each of the 3 lugs on the transistor was bolted to a 1/4" thick copper bus bar.

Well we were running tests one day and apparently one of the gate drivers failed pulling one of the IGBT's on, which when the second one turned on it created a short. The battery pack supplying power to the controller can source well over 1000As for a decent amount of time. Needless to say I have heard gunshots that were not nearly as loud. The IGBT blew its top off separating itself from the HS mounting plate and deforming the 3 1/4" bus bars connected to the top by several inches.

Nothing all that exciting.... but still had some force behind it:

Wow, well I haven't really had anything blow up, the closest was when I was building my very first Cmoy. I accidentally inverted one of the power caps, I had one in backwards and when I applied power to the amp, the top of the cap bulged up. Kind of scared me, I wonder what would've happened if it burst open. Anyone see an electrolytic capacitor explode?

I've blown up a lab ps and a computer ps. Crashed at least four hard drives and i've zapped myself with a big ass cap. Fried a motherboard, killed some ram. damn.

OUCH!

When the iron hit the live power supply wire it let off a spark bright enough that I could see the afterimage for several hours. The resultant shock killed the power supply, three hard drives, the fan, and a CD-ROM drive. Somehow the motherboard and CPU survived. And when I say killed, I mean dead dead. All three hard drives smelled of burnt silicon. One of the hard drives would rattle when shaken! A very expensive lesson

wait, what? Shouldn't you just've attached a molex connector onto the fan?
What on earth were you trying to do?

I was testing a 6dj8 tube on my TV-7. It was reading really, really, really strong. I thought I had a winner on my hands when I noticed the tube was glowing extra bright. Turns out I had the filament voltage set to 12.6 instead of 6.3 v. Whoopsie.

The tube still tests OK with the filament at 6.3 v, I guess I will have to test it in an amp one of these days. It was a nice Amperex, too.

I tried converting an Abit BD-7 Raid motherboard into a board that would support four P4 Northwoods. First run, it gave me a light show I'll never forget.
