[King Zultan]

Is it a Jacob's Ladder?

[EuchreJack]

Nah, it's neither. The ones I've seen come to a point and the electricity arcs off that.

I was asking because I saw a video where someone stabbed a dead prawn onto one, and all of the prawn's legs, antennae and other points started shooting arcs.

Maybe it's not so harmless then.

[GiglameshDespair]

I mean I don't think the prawn was feeling pain from the experience

[scriver]

Cancers have feelings too!

Maybe after it came back to life...

I wonder if prawns have enough metals in their exoskeleton to allow the charge to flow over their bodies without frying their insides.

Probably not.

Probably not.

Tesla coil arcs, along with most of these demonstrative arcs, are high voltage, low amperage and low power overall. So it likely didn't do much. The electrons are high-energy enough to ionize molecules but there's not enough of them to transfer much energy.

Jacob's Ladders will kill you though.

[Eschar]

The prawn was already dead.

Kenshiro when he sees the corpse of an animal jerking around due to electrical shocks: "Omae Wa Mou Shindeiru?"

[King Zultan]

But can I cook my prawns with electricity?

"Omae Wa Mou Shindeiru?"

But what does it mean?

[hector13]

Reasonably sure it’s from Fist of the North Star, in which the main character’s catchphrase has been memeified.

You don’t know it but you’re already dead, or some such.

This kills the prawn

[Great Order]

Found out that the effect I was seeing in the video was coronal discharge, so that should help me narrow it down.

Now, another question.

Is there a way to protect electronics from a geomagnetic storm? I got curious and I'm seeing that apparently faraday cages wouldn't work on one, although I'm not sure why. For that matter I'm not sure why faraday cages work anyway, but I'm not too fussed about finding out about that.

[McTraveller]

Faraday cages only stop EM radiation, not near-field induction.

But yeah you can protect against geomagnetic storms.  Without looking it up, I think you just need good magnetic shielding (a solid metal enclosure) and appropriate injected current protection.
