I just tested a "Energizer Max" 9V battery, brand new from the
package. Short circuit current was 7.3 Amps. Note the lack of
"milli."

I seem to remember testing a NiCd 9V once and finding that it
could produce even more short circuit current.

I've tongue tested (as have probably just about everyone else) a fresh
9V battery, and your battery isn't that much more. Should have given
you a bit of a twinge...

I suspect the internal resistance of the battery limits what can flow
through your nice, wet tongue. I don't remember the short-circuit current
of a typical 9V battery, but it seems to me the last time I tested one
it was in the tens of milliamps.

Which brings to mind an old urban legend. The termianls on a 9V battery
mate quite nicely. How long until the connected batteries explode?

Seems to me wet tongues have more resistance than fresh 9V batteries.
At least alkaline ones. I can usually light up a 93 bulb with one, and
that takes nearly an amp. Sometimes a 9V battery can light up an 1156
bulb, and that requires well over an amp.

Look in ABSE for my attachment - a .gif of Carl & Jerry roasting
weenies and talking about shock current and skin resistance. I only
have the one page, and it was tattered and torn. Amazing it came out
as good as it did. It's frm P.E. Feb. '59. Just look for Carl &
Jerry.

But then most of life is like that. It's only a matter of time before
something you do gets you. Like driving, it's only a matter of time
before someone gets into an accident. Hopefully not fatal. But then
more people die in auto accidents than any other accident. So does
that stop us from driving? No.

In this case, I used the term accident to differentiate between that
cause of death and death by natural causes, such as cancer. So you
could put quotes around that term.

Tom was working on a TV chassis which was sitting on its side, power
applied, cable attached. Tom bumped the cable, and, before Tom's
magnificent dive to the Sencore isolation unit's power switch, the
chassis bottom made contact with Tom's left forearm. Tom was left with
dozens of burns from the various voltages present.

Fortunately they were only burns.

This didn't even compare, though, with the time that Tom tongue-tested
a cellular telephone PS, 10.6VDC, 850 mA. OUCH!!

Oh no...this was MUCH more than a 9V battery could ever provide,
believe me. I thought the top of my head was going to come off.

I can remember my dad working on a TV set on the bench. Got an arc to
something and jerked backwards pulling the set off of the bench and it
fell to the floor. This was in the days of picture tubes strapped to
the chassis. The chassis hit flat on the concrete floor, just about
every tube popped out of their sockets and broke, but the picture tube
didn't break ;-)

The power supply output would be 10.6V at 850mA, but much higher when

no current is being drawn from it. This is normal, and you were
probably getting more like 17 volts. OUCH!

What a joke. Your tongue isn't enough of a short... at all to pull
such a battery or even single cell down.

In any case, they sure as hell don't produce that much through a
tongue. Any tongue. At std nine volt battery terminal spacing.

Much simpler: Put a little dry ice in a plastic drink bottle, like bottle
water comes in.

Add an inch or so of water. Cap tightly. Run away!

The 1/2 liter bottle will swell up to the size of a football before
exploding with a bang reminiscent of shotgun blast...very loud. Sometimes
it takes a few minutes, sometimes longer. If you don't use enough dry ice,
it only swells. Don't touch it, it could still blow. Throw a rock at it
first, or just leave it alone..

The following can be fun too: Fill a vessel up with salt water. throw
in two carbon rods connected to a car battery charger.
Run it a while till most of the chlorine has gone out.
Power off, put on a lid, hide behind a wall, power on and run the
generated gass into a SMALL baloon. Power off when 5" diameter.
Use a light plastic lid that will pop off and not hurt anyone if the
gas in the vessel ignites.

Then hold the baloon at arms length, close your eyes and take a match
to it. Do it with your hair wet, in wet smim trunks next to a swimming
pool so you can jump in if you catch fire. We had great fun with this
as kids. It is not unbearably loud but generates an incredible bang
and you feel a heat pulse similar to what you get when you set off a
large photoflash right against your skin.

Skiers have been known to use these contraptions in 2-liter drink bottles as
home-made avalanche bombs. One twist - they use urine instead of water to
initiate the blast (more available on a frozen moutainside).

That makes sense. The current wouldn't be zero or even close, but much
less than 850mA, I suppose. It was a real buzz, anyway.

I expect it's much warmer than any liquid water available there, as well. I

can only imagine what a two liter bomb would sound like. Like I said, the
1/2 liter ones are amazingly loud.

OK Watson, I give up. What effect does it have on the cat??

If you haven't got a cat, then paint a little on your bum!

It's a bit rougher and harsher than the finger covered in ginger up the Arab
horses bum, to get it to lift it's tail for the showring!

And you though it was natural to have that high tail carriage!
