"Plasma ball" Christmas tree   (+4)  [vote for, against]
Unique

A conical glass enclosure - sizes vary between 200mm and 1500mm tall - with a tapered core, on which are rings at different voltages to produce the "branch" effect of plasma tendrils. Argon gas would give the green colour.

Prior Art acknowledged.

Do not water.

"Tree" idea mentioned in [neutrinos_shadow] annotation. [8th of 7, Dec 06 2019]

How low a pressure is needed to sustain the plasma? Could one convert, say, a mid-sized conservatory into a low-pressure oxygen chamber complete with plasma? I know I've seen a guy who wears a chain-mail suit and pulls huge arcs from Tesla coils.

//..1500mm tall//
Why so small? Gas pressure issues notwithstanding, it needs to go at least to the ceiling, if not "we're going to need a bigger house" size.
