I just knew which video is linked without clicking. ElectroBOOM is a treasure.
And yet I learned something. In nearly 50 years of playing with electronics I've never seen such a beautiful LER (light emitting resistor).
Edit: I am disappointed in his hooking up his oscilloscope ground to some random point of the circuit. Did he really do that? It sure looked convincing on the video.
It's something that everyone using scopes learns not to do very early on. It can't be good for the wiring in the scope.
Though probably not due to current, likely someone took a torch to it to try to make it easier to remove, and then took a picture. Then again those connections are vastly undersized for the cables...
