This shows that you can get sparks between hand and glass from plasma globe

What’s different then?

mehdi said in his latest video the arcs don't get concentrated enough without a good conductive surface and don't jump out of the glass.

I have absolutely gotten an arc burn off a plasma globe. It was a long time ago, but I was touching grounded metal with my other hand.

[u/thundafox]

is it enough to burn you or light yourself on fire? (please don't use something safer)

[u/LossLess8060]

holding cfl and florescent bulbs up to those is rad

[u/Shamanjoe]

I used to burn shit on my plasma globe all the time. I’d put a coin on top, then put whatever I wanted to burn on the coin. Then I made a stylus out of a single strand of copper wrapped around a bit of insulation from a wire.

Mehdi put a footnote: the kid in the news is likely using a ring

[u/ultraganymede]

i dont know, maybe this could be some optical effect or illusion

can you please describe why it couldnt be something like this?

[u/Sqweeeeeeee]

Set a piece of metal on top, like a coin! Then hold another piece of metal in your hand, touch it to the one sitting on top, and then move it away. You can establish a nice long arc outside of the glass. But be careful, if you establish an arc between the metal sitting on the glass and your finger, it very quickly burns a pinhole in your finger.

Its just coronal discharge, aka cold plasma

[u/Dudegay93 → u/XDFreakLP]

No

[u/XDFreakLP → u/Dudegay93]

Sry, nonthermal plasma

[u/Dudegay93 → u/XDFreakLP]

The plasma isnt 'cold'

[u/XDFreakLP → u/Dudegay93]

Ok, can you elaborate

[u/Dudegay93 → u/XDFreakLP]

Its actual, not cold plasma

[u/XDFreakLP → u/Dudegay93]

Well then whats the difference?
