Fellow electrical engineer as well. Yes, even a seasoned electrician and or field guy can be hurt/killed while having knowledge of the voltage ratings. It is that easy to ground yourself in a panel or accidentally touch something. Also, in some high voltage situations such as utility disconnects, dust across the phases can cause arcs and implosions when the circuit is turned down/on. That is why many electrical rooms will have a small amount of positive pressure to keep the air dust free and clean. I do not recommend anyone play with high voltages such as these for art projects. These types of ratings need to be respected and always handled in a controlled environment. The guy posting this video is right. Do not attempt this at home. Just let it go and move onto something safer. It is not worth your life.
