Trying to use molecular script for Blender, but unfortunately, it can't be seen very clearly in this footage. So, I'll put a picture to become more clear.

 

Using Blender 7.9 Alpha. Cycles with OptiX AI- Acellerated. Really amazing to remove the noise!

It seems a simple effect, but to make this plasma I had to use Gradient ramp, Colorama, Curves, CC Cylinder,CC Glass, VC Color Vibrance and Glow!
