This channel in particular is less about Lego than mechanics and experiments, so adults have plenty to enjoy from the videos. There’s a video about building a quadcopter for instance, and bricks are used for the frame but he’s also be soldering to have what he needs on the chip.

And you’ll see magnets, metal axles, non Lego controllers, survolting etc. Highly recommend for anyone curious about funny practical experiments.
