Aqueous electrolysis is that sort of thing that even a 10yo kid can do at home*. Igneous electrolysis though? Chemistry knowledge isn’t enough, you need technical skills. He clearly had none at the start of the video, that’s why it took him so long - he learned it as he did it.

*I did it with small plastic soda bottles, pencil leads, aquarium tubes, and super glue. I stopped using it after I found a better source of hydrogen - aluminium cans and lye.
