Certainly you're not suggesting using a 9V battery this way -- you'd
never
get enough current to harm a flea ... well, maybe a flea, but probably
not a
human.
=========================
OK, I'll play along. How much current do I need? How much voltage? 9V
.1A in, we could get maybe 900V and 1mA or 9KV and 100uA. You grab that
and see if it tingles.

Back in the Stone Ages (~1967) I was working with image-intensifying vacuum
tubes and one setup had a 30KV Spellman bench supply, maybe a milliampere or
so. I took a few shocks from that, including one from the eyepiece of the
microscope I was using to examine the image right to my eyebrow -- knocked
me across the room, but I'm still here to tell about it. The amount of
current needed to kill varies widely with the path the current takes thru
the body. Naturally it takes less if it enters near the heart than if it's
in the legs. I'm sure there's plenty of information on shock hazard limits
on the web.

I stuck my right little finger into one of the final tanks of an ARC-51 UHF
radio while bracing my hand to blade-track-tune the adjacent tank. About
600 Volts at about 400 MHz. Nice lttle black hole right through my finger
and fingernail. Still typing with that finger.

Good idea. Also, think dirty sock, when it is filled with
batteries.
This has been used for robberies for many years...
.... just an old muggers trick...

With my kid's dirty sweatsocks you won't even be needing the
battery...

Explain pleasy...

The sweet (=acid?) in the sock helps to transfer the current from the
battery onto the guard ? is that it ?

Sounds great. I have many stinky socks hahahahahahaha I love this idea
hahahahahahahaha it's so diiirrty hehe.

Bye,

Rapid kinetic energy dissipation.

If the first attempt at making a drawing board had been a failure,
what would they go back to?

You think too small! Use a forklift or a locomotive battery. ;-)

You need to blind the victim, throw sodium choride in his eyes then drop
the battery on him. That would be a real case of a salt and battery!

Just chain the victim to the counter at an all you can eat restraint
and yell "Free food!" to a bus full of people who just got back from a
month at fat camp. They won't have enough left to do an autopsy after
the hungry mob is done trampling him.
