I have some revealing photos of a discharge from "The Jar". the first shows the origin of the discharge. (This is its birth place) I have noticed that the effect comes from the sparks that are present at the time of discharge. This is how I could produce two bursts at the same time in my conventional Gray tube. But this is a photo of my multi-gap.

This is the same discharge, clearly showing a plasma ball leaving "The Jar" I get this effect a lot the plasma ball leaves the Jar usually going strait up.There is even one in the still that Aaron posted (Thanks) thats completely left "The Jar" and the main discharge.

And this is the first time I have seen this! the plasma, as the burst is diminishing, seems to be drawn back into the LV electrode. (which is a hollow carbon fiber arrow shaft. I have attached a round ring of copper around the carbon shaft's end that is inside the tube. Maybe thats what the plasma is drawn to. Anyway Here it is.

This was a small, slow burst , almost like a burp.

Enjoy!
