When I was growing up, we had discovery channel. That sparked my intrinsic curiousity. My daughter has that intrinsic motivation as well, but only for k-pop now. She likes youtube videos and she likes when I tell her about science stuff. Maybe I can combine that by recommending her some good youtube channels.
If we’re being pedantic (which I’m all for), the sounds aren’t switched 1:1 exactly.
German z is usually a ts sound, like the tz in hertz.
German s is indeed commonly the same bu**zzing sound as English z (but it can also be a sharp hiss**ing **s**ound).
An approximation might be [koorts guh zaakt].
