That's why pressure is measured, "per square inch", or whatever
measuring standard yer using. Even normal atmospheric air pressure is
14.7 psi, which is why if you pull a vacuum on a 1 gal metal can,
atospheric pressure, alone, will crush it like a grape. Was that
wallwart 2"x2"? That's 4 sq in. Times 50psi air pressure? That's
200 lbs of pressure exerted on that cheap plastic bottom plate. Is it
any wonder it blew off?!

Ironically, no transformer/wall wart ever came apart more cleanly. I would
normally have had to Dremel it apart and that would have made a hell of a
mess and would have required taping back together. A few drops of
solvent-weld glue and this baby will go back together with almost no
evidence it had ever been "blown open." In fact the jagged(!) seam edges it
left fit together like a jig saw puzzle piece.

A little dab of hot melt glue in the access hole and I'll be good to go.
Next time I do this, it will be with the unit mounted in a vise inside a
containment vessel of some sort, i.e. a heavy Tyvek envelope or similar.
Probably another case where St. Peter will explain to me "nearly put an eye
out then!" along with all the other near-misses of my life. With my luck,
the next one won't break cleanly along the seam, but into a million shards,
but it will be in a vise and a bag, not in my hand.
