Re: Ball Lightning



Oh, this was regarding "upside-down plasma pools", where you capture a
microwave ball lightning in an inverted glass bowl within the oven. The
"bl" expands into a buzzing pool of glowing matter, then changes from
orange to pinkish-violet and starts spewing out oxides of nitrogen, etc.
Salt crystals on the glass bowl's inner surface, if they drop off, will
dope the plasma-pool and create bright sodium light. You can see the Na+
ions migrating through the plasma as a fast visible wave of orange.

These things are as hot as a flame. I've lost one pyrex cup measure and
many small pyrex custard cups during efforts to entertain colleagues.
Putting some honey and NaCl in the cup will produce brilliant flares of
sodium yellow light as the honey warms up and releases the salt crystals.
I'd heard about a "microwave sulphur" light source, but it doesn't work in
N2/O2, just creates very irritating fumes.
