Ball Lightning
John Schutkeker
You should all find this to be interesting, but somehow I thought that the
discharges were larger, like a foot or two in diameter.

(yawn)
Show me one going through a plate glass window without leaving a
hole and I'll be impressed.

Thank you, nice movie.
Some interaction seems to happen between these balls and them and the wir=
es.

WooooW! This is so totally cool. Looking forward to all the movies. IT
looks like it has some particles perhaps metallic that are burning and
they are jumping!

.... hahahahaha... that happens every time you do welding.
It's called splattering, excess molten steel, that falls off
either by Acetylene/Oxygen flame cutting or when bead
welding with older models of electric A/C arc machines
when incorrectly adjusted or when the electrodes are moist .
The little balls of light you see are nothing more then molten
Fe beads that burn up/get oxidized by the air. And they jump
when near/on something organic (cable) because they do
liberate a puff of gas from the momentarily scorched rubber,
or from oil or water spot on the floor.
Thanks for the laughs, guys. Go buy some sparklers and
have yourself a merry old lightning ball fiesta... ahahaha...

I haven't noticed. What do you think?
Here's another movie next to that one:

Yes, sparklers, burning bead of Fe, Al, ... That is exactly what this guy's
theory of what causes the lightning ball is all about. The video sure looks
like burning Fe, a component of Solid Rocket fuel. In the case of the
lightning balls, the theory is that the Lightning strikes the sand, silica,
SiO2. The SiO2 disassociates (SiO2 + energy -> Si + O2) from the lightning
strike, creating a cloud or aerosol of just pure Si. At some point it
ignites, forming a big ball of burning Si (Si + O2 -> SiO2). Just like the
burning splatter of Fe from a welding rod.

...A more down-to-earth theory, proposed by John Abrahamson and James
Dinniss at the University of Canterbury in Christchurch, New Zealand, is
that ball lightning forms when lightning strikes soil, turning any silica
in the soil into pure silicon vapour. As the vapour cools, the silicon
condenses into a floating aerosol bound into a ball by charges that gather
on its surface, and it glows with the heat of silicon recombining with
oxygen...
