Har har har...

Yeah, "plasma ball" seems descriptive, but I was thinking it had some
cool-sounding scientific name...

What, like "plasma ball"? I don't know about you, but to me "plasma"
sounds both cool and scientific. IIRC, the ball is filled with very
rarefied gas -- somewhat like a plasma. :->

Plasma globe. Usually (the typical blue tendrils, orange footprints 
variety) filled with Ne and He in a vacuum (mostly He. The bit of Ne. 
gives the footprint the orange glow)

I actually own one of these. 8-)

Me also. (The footprints are pink.)

I also own a second one - it's really weird. The surface is the glass is 
opaque, but when it's on you see randow colours glowing through it. (I 
imagine the glass itself is coated with some kind of phosphore - the 
colour seem to stay on one side of the globe...)

I think the contents of the globe might actually count as "plasma" too...
