I've had a beercan-sized cap (a proper UK 500ml

spectacular fashion. To be fair, I suspect that a failing rectifier had
already administered the death blow to it.
The most dangerous, in my experience, are the old steel-jacketed,
epoxy-sealed Sprague "Vitamin Q" caps (not large electrolytics)
sometimes found in miltary equipment. I've got a mark in my ceiling
where that steel jacket embedded itself when the cap blew.
