Hello, I have another simple question.

How to replicate this effect? Your suggestions.

My opinion is that these are electrical discharges on a metal plate.
The following questions follow from this:
1) How to repeat the experiment with so many discharges (I have a strong impression that one discharge is formed during breakdowns).
2) How to achieve such discharges at home with a "lamer" (can I use a choke from gas-discharge lamps?).
3) Give a sketch of the installation.
4) What shooting speed is required to capture such frames.

Thank you in advance for a number of answers.
PS I am attaching a photo.

Apparently, these are corona discharges.
If the conditions coincide, voltage, current, humidity, they can be formed randomly on any microroughness of a flat surface.
There is no breakdown there, this is exactly the crown, one photo shows a breakdown, and there is just one powerful lightning.
It is possible that all this happens in a closed volume with a certain pressure inside, or even in some kind of gaseous medium. In principle, nothing complicated and you can repeat it in the kitchen, but you need to know what exactly they are doing there to make it look like.
