"Factories are just rooms": demystifying manufacturing for 7-year-olds

The maker of an AI clock recounts a school visit where he walked a class through how his product actually gets built — from exploratory sketches and CAD to breadboards, PCBs, e-paper screens, and injection-moulded plastic parts. He handed around real prototypes and iterations, showed factory-floor photos from his Shenzhen manufacturing trip, and contrasted a year-long 3D print of his clocks with a single day of injection moulding. The kids, who already knew the word “prototyping,” asked sharp practical questions: how does it survive shipping (vibration testing), how does the button work (assembly and industrial design).

His explicit argument is against the genre of factory footage engineered to inspire awe — thousands of products whizzing by on parallel belts. Awe, he contends, tells the audience to step back and admire from a distance, like a painting you’re not part of. He wants the opposite: to “re-home” manufacturing so kids see the chairs, TVs, and plant pots around them as things people invented and figured out, not divine objects. The pitch is that complexity is fine and that any of them could become a designer, engineer, or maker.

The piece doubles as a call to action for other adults to visit local schools and normalize hands-on making while kids are still forming their sense of what’s normal. The author frames himself as “just someone’s dad” to underline the point — the barrier to becoming a maker is lower than the awe-inducing imagery suggests, and the hoped-for payoff is a kid who later thinks “someone should fix that” and realizes that someone can be them.
