Subject: Mysterious exploding fish

OK skeptics and scientists, please explain this event, which happened
here in New Zealand yesterday:

A women was preparing a flounder (a type of flatfish) for cooking.
She had cut off the head, and was slicing along the backbone with
a sharp knife on a wooden cutting board.

Suddenly, there was a loud bang and a flash of light!  She called
the police, and investigation showed the following:

 o  There were burn marks INSIDE the fish
 o  A chunk of the metal of the knife had been taken out

The fish had been purchased recently from her normal supplier.

Explanations, anyone?  This is *not* an urban myth.  It happened.

hmmm... i'd be interested in the proof, but that's another matter...
explanations:
 1> the mercury content in the fish spontaneously produced mercury fulmanate,
 which is a mild percussion explosive (this is, many would say, impossible)

 2> white phosphorus deposited itself somewhere in the back of this fish, in an
 air-tight envelope. once exposed to air it exploded (this is, many would say,
 equally impossible)

 3> high radiation levels from the bikini atoll nuclear bomb testings have
 finally produced the first mutant exploding fish, precursor to the ert-teldens
 of the gamma world role-playing game (this is, many would now insist,
 absolutely impossible)

 4> this was one of the bizarre occurances that keeps publications such as the
 sun and weekly world news

Decomposition had caused a small amount of methane to collect
in the fish's intestine or other internal body cavity.  By
rare coincidence (a) the concentration was great enough to
support ignition and (b) a single action of the knife managed
to cause this.

Strange... the only possible explanation I can think of is that somehow,
someway this fish swallowed something like part of a magnesium flare, and
that his body somehow swaddled it in a protective cyst. When the woman cut
into it, she exposed the magnesium to air and it ignited.

This theory ought to be easily disproved or proven by close examination of
the fish -- please keep us informed if and when anything more is learned.

A really interesting case.

or by the fact that magnesium doesn't ignite from exposure to air
 and magnesium quickly forms Mg(OH)2 in water; more quickly than a flounder
could swallow it...
 and a flounder is hardly large enough to swallow any part of a magnesium
flare.
 the list goes on and on :)

Perhaps the fish swallowed an unexploded cartridge it found at
the scene of a WW2 battle.  The remains of the cartridge may have been
flicked away by the explosion.  I've heard that some old ammo can become
really unstable, due to formation of metal ion complexes between the
powder and the casing.

A-HA! Yup, it's an old story: we tend to assume that we've
been given all the facts and construct our theories without
asking further questions.

Shorting out a lamp cord, then denying the possibility out
of embarassment is far more likely than mercury fulminate,
methane explosion, WWII ammo, etc.

How easy it is to forget to be skeptical when presented
with a novel mystery!

        "bullets", per se, are not explosive.  Use of an exploding round is
_so_ unlikely in this cas as as to be unlikely.  On the chance that 3 & 4
don't resolve it, are these fish "bottom feeders"?  In the "bad old days"
various sorts of things, specifically including obsolete or unusable munitions
were dumped in the ocean.  Any sort of small arms primer would, i think, match
the description.  Should be traces in the fish remains.

You are thinking of sodium metal.  White phosphorous is stored under
water, since it is not stable in air and it is highly toxic.  Red
phosphorous is stable in air and is the form that is used most often
commercially and it is not very toxic. Sodium metal reacts violently
with water and is stored under kerosene or mineral oil.

Oops, I meant PHOSOPHORUS, of course, which as I proved in school explodes
violently when put in contact with WATER...(thus it is sometimes stored
under kerosene). My "cyst" was to keep the stuff out of contact with the
water natureally in the fish'es body...and uh, the fish was supposed to have
swallowed part of a rusted out old flare near a WWII plane crash or ship
sinking.

Then again, maybe the ditzy old broad just cut into a lamp cord.

We didn't have any WW2 battles down here in NZ.  Plus a flounder has
a very small mouth, and would be unable to swallow any portion of
a cartridge large enough to retain its envelope integrity (i.e. keep
the powder dry).

Police forensics have not found a bullet anywhere, and anyway, the spent
cartridge should also be in the room, thus doubling the chance of finding
something...

Can some other NZ net people comment if you have heard any more?  I know
that fisheries research are on the net... c'mon guys...

Or quite possibly metalic potassium.  Though sodium does give you a bigger
"bang", gram for gram.

WRT the fish ... I don't suppose this could have been a previously undiscovered
species of "blowfish", could it ...?

kitchen on Friday has fisheries scientists puzzled -- but a clue may lie
in whether the unfortunate fish had been filleted.
        "The elderly woman, who declined to talk about the incident
yesterday, told police she had been cutting the spine of the fish when
it exploded.
        "The explosion burned the fish's insides and left burn marks
on the knife and wrapper.
        "According to Agriculture and Fisheries Ministry pathologist Mike
Hine, the only explosive substance found in fish is methane gas -- which
was highly explosive -- and the woman may have released the gas when
she cut into the fish's bowel.
        "But he said 'a tremendously strict combination of the amount
of gas, a flame, and ignitiion' was need to set of an explosion.
        "'I've been a professional scientist for 20 years and I have
never heard an account like this before.  A lot of fish I cut up do
have gas in the bowel and it is methane, so it would be expected, under
the right circumstances, it could happen,' he said.
        ...
        "Another possibility is that the explosion could have been
sparked by a buildup of static electricity, not in the fish, but in
the knife and the bench used, according to the ministry's fisheries
research head, John McCoy."

SO the case of the mysterious exploding fish is not yet solved, but
will no doubt be added to the store of unexplained events...

Some of the other explanations put forth may work in
conjunction with the following, but there have been
cases in the literature describing incidents where
relatively unknowledgable folks have mistaken electric
rays for flounder. In some cases, the mistaken individuals
have fileted and eaten the rays (which supposedly do
taste pretty good!). In any event, I would think that,
since the electric organs run along the backbone of the
ray, there is certainly a good possibility of "shorting"
the tissues through the knife blade...don't know if there's
enough power there to melt the blade, and I don't know
whether the event would cause any acoustic side-effects
(like the "popping" sound you get when you short out a really
big capacitor), but it does provide one more possibility!

Naw man, who'd believe a lotta hooey like that?

What really happened was some space monsters--you know, chariots of the
gods type guys--were down there looking for Elvis.  Anyway, they were
trying to get the King to chanel through a fish when that dizzy old
broad hadda go ahead and stab the fishy, effectively ruining all short
term hope for seeing another Come Back Tour--at least in this astral
plane, anytime soon.

Don't believe it?  Just ask the FBI?  They got files on the whole
thing.  They found out about it by running a wire into Shirley MacLane's
medulla oblongata.  I got the transcripts through personal connections
in the CIA.  I can't say anything else about this stuff.  I know you
probably want to know more.  This is just one of those times when you're
going to have to put national security ahead of your enquiring mind.

Gotta go.  My wristwatch is ringing.

Maybe someone had gone "fishing" with dynamite, and that flounder is one
that took the bait and got away?

Magnesium does not ignite spontaneously--nor should part of a flare.

Several people have suggested that the nearby electrical cord was
involved, and I go along with that, mainly on the strength of the
missing chunk of metal from the knife. Most postulated kinds of
explosion simply couldn't do that. On the other hand, this is exactly
what I would expect, on the basis of personal experience, from cutting
into a wire. (Years ago, moving into a new--to me--apartment, I found a
length of twisted lamp cord that emerged from the woodwork, ran along a
few feet, and disappeared under the wallpaper. I went to remove it with
a kitchen knife...)
    A key observation would be whether there are in fact _two_ chunks
out of the knife, or a single chunk with two lobes, with the distance
apart being comparable with the distance between the conductors in a
typical electrical cord. When one slices into a cord like this, the
greatest current density is in the immediate vicinity of the two points
of contact between the conductors and the thin edge of the knife. If the
damage to the knife is this shape, I would consider it to be conclusive.
    Even if there is only a single, roughly semicircular, piece missing,
it could be that the blade only contacted a single conductor, and the
circuit was completed through the fish, the wet cutting board, and
whatever, to ground.

As noted in another posting, she _did_ think she was cutting into the
spine of the fish, so the feel of cutting into the cord would not have
been unexpected.

The fact (reported in another posting) that the person concerned is no
longer talking about the incident is also suggestive.
