Oh ya........... is their house still able to produce/use electricity & water despite not having the sources from their original world/Earth? What about the TV? It'd be interesting to know, as the question about the vacuum came up lol.
Because I'm imagining how we have to explain to a native if we're Isekai'd, about electricity & water that we can get from dams & tanks... Like, "electric is just domesticated lightning, kind of, that we produced via a machine called the dinamo we built inside a dam. & the water, we get from..." etc, like that lolol.
