We had a situation where the center tap on a local distribution
transformer got crossed with one of the phases. It resulted in one phase
going to ground potential, and the second phase going to ~~ 220 volts.
Everything 110V on the dead phase was unaffected (because it was dead),
and everything 110V on the other phase got fried (because it was at 220V).
I had gotten up that morning, and I heard our pool pump kick on, which
was a 220V motor wired between phases. Sounded like a "normal" morning.
Walking through the family room on the way to the kitchen, I flipped on
the light, and POP! The light in the family room literally exploded.
Weird I thought, but the pool pump is running normally.... Not having
had my coffee infusion yet, I proceeded to the kitchen. I flipped on the
kitchen lights and POP! another light bulb explosion. Now it had my
attention.
I went into the garage, and grabbed my DVM (making sure not to turn
anything on). Going around the house I found some outlets dead, and some
reading 220V. When I encountered the first one at 220V, my next stop was
the main panel, where I flipped off the main breaker.

I am wondering if you hit a light bulb with enough voltage to vaporize
the filament will it over pressure the envelope enough to explode?

Must have forgot their tin-foil towels.
I don't know what the voltage would have to be to jump a light switch,
but I can tell you that I've seen it. A few years ago, a tree fell in
my sister's neighbor's yard and knocked the primaries down on top of
her secondaries. So that was at least 12-13kV. It was ugly. Whole
house had to be rewired.

Seriously...
When they publish things like this:
"With that flash, every lightbulb in my house had exploded! The
old lightbulbs merely popped and shattered. Those new lightbulbs
(CFLs) were on fire! I could see smoke, smell burning plastic. I
had no idea what happened."
So, every lightbulb was on? If not the overvoltage jumped the
switch? How much of an overvoltage event does it take to make a
lightbulb pop like you see in movies? I have never seen it happen.
Especially difficult when the switch is off.
All this happened because of a smart meter?
And later:
"All the while I was experiencing more electrical issues and
finding more damage. The craziest thing that occurred was I
literally was shocked getting into the shower! I went to grab the
nozzle to direct the water down and when I grabbed it, I
literally got a jolt of electricity, my hand stuck, my knees
buckled and down I went. I didn’t take a shower after that,
needless to say.
When I came downstairs, I heard water and could hear popping. The
main water line from my well had exploded and electricity was
sparking from it."

Seth, was that meant to be tongue-in-cheek?
