Re: Holy Crap!

Hi,

If the current passes through the ceramic and not around it, it would be a significant resistor. If it presented around 100 ohms, that would explain the low currents mentioned in the artical. The tube would heat quickly and spray steam and then arc inside the tube. Sort of a steam plasma torch effect.

The firing and getting it just right might be fairly complex in that case.

Cheers,

Hi Terry,
It is a small tube made of unglazed (porous) ceramic. It is "Techno-slanguage". Imagine a German-speaker looking up "pole pig" in a general usage English-German dictionary. Same problem.

Sort of sounds like the insulating tubes used in "knob and cleat" writing but probably smaller. The fact that it's unglazed may not matter and glass tube (or even plastic if there's not a problem with melting) would probably work as well. As to the meaning and results of the experiment that's another matter.
