I can't watch Electroboom because he always gives himself shocks in every video. Don't care that they are small or it's set up, I can't stand watching it, makes me ill. Seems to be interesting stories he's telling otherwise though, so it's a shame.
Mehdi/Electroboom shows you what you can do, and why it's dangerous; usually by shocking himself, blowing something up, or having stuff catch fire. He isn't teaching mindless, disprovable safety culture, but showing you the actual boundaries you have to respect. As such he has both videos of "let's shock me with lowly increasing voltage to see when it starts to hurt" and "ranting about badly wired wall sockets and lack of GFCI in this hotel room".
If you show a kid a video about someone intentionally putting e.g. a fake hand on a stove and it getting severe burns and faked screams, what's the likelihood of a child following the video to get the same sick burns vs a video showing that it is perfectly safe to touch the stove?
