Sorry, kid has long grown up and moved out. I guess I’ll get a second wave when grandkids start appearing. But any bookshop kids’ section will have heaps of them. IIRC Gerstenberg Verlag was a good source, but that was a while ago. Also the Was ist Was series had the best explanations of how real stuff (locomotives, printing press, sexual reproduction, etc) works. If you can’t find the books I’m sure some of the videos are on YouTube.
