Learning to communicate with the young generation - Twinline(TM) Technology adapted with LEGO bricks

Sat with my younger son (7) helping him with some LEGO creations, after having helped him my mind spun off in a different direction and I started to create a model of the Twinline(TM) inline separator (bulk separation of gas and liquids). With some creativity I was able to put together something that I think modestly resembles a Twinline model as a simple and quick build. My son asked what it was and for him it was enough to hear that it had to do with oil production/separation. A bit later my daughter (11) came by and got curious. She wanted to know many more details on how it works and for what it is used. Seems like my experiment got some attraction in my small test environment. Anyhow, I think this shows that kids find interest are curious about a lot of things, even machinery and technology. Guess this also showed me a way to communicate with them that catches their attention. For my older son (teenager) I probably have to do an app or similar, perhaps that's next. In the picture, if you can't recognize the difference, the LEGO model is on the left, comparing with a drawing and a real installed unit (not all parts visible).
