Default Its a weird questions but......

Today I was in a big toy shop. There was a plasma ball. You touch it and a lightning bolt went from the center core to the spot on the inside surface of the globe right under my finger. As I moved my finger around the bolt moved with it. It got me to thinking what would happen if a person was touching that globe and died. At what point would the bolt of lightning stop? Does anyone have any ideas about this?

I would think when they stopped touch it.

I never tried touching the globe with a stick to see if the bolt was attracted to that. I just got to wondering if a person's life forces as they ebbed with death that the bolt would lessen too until there was no effect at all if the hand was in constant contact with the globe.

As far as the 'lightning' is concerned, you're just a wire connecting the outside of the globe to the earth so you make an easy circuit which it uses. Dead people conduct electricity just as well as live ones so as long as the contact ramains the lightning will travel through your finger.

When there's nothing touching a Plasma Ball, there are multiple small plasma filaments extending from the inner globe (electrode) to the outer globe (insulator). When you place you hand, or if any conductive object approaches the outer globe, it disturbs the electromagnetic field, and all the small plasma filaments are replaced by one big one.

There is no danger to humans (or even to small animals), since, though the voltage is high, the current is very low. So it's not likely that a Plasma Ball could kill someone. And if they happened to die while touching a Plasma Ball, as MartinSykes has said, a dead body will conduct electricity just as well as a live body, so the effect of a body, living or dead, would be the same. Plasma Balls are unaffected by metaphysics.

But a Plasma Ball can be harmful to electronic devices.

Note that those are two separate assertions!!

I can think of some awesomely fun experiments that could be done to prove this one way or the other. I suspect that dessicated bodies (mummies for example or perhaps some kinds of zombies) would not be as conductive and hence not much use for plasma ball displays.

Anyone fancy a day trip to the morgue? (Plasma balls provided, but bring your own philosopher/mummy.)

Ok, there's a difference between "dead" and "dessicated".

I also think it's unlikely that you would find a "dessicated" body in a morgue.

And, btw, embalming fluid conducts electricity too, so a dead body that has been embalmed will affect a Plasma Ball in a similar way that a live body would, though possibly not to the same degree. But since embalming fluid can be as much as 50% ethanol, you might want to be careful about that.
