Bill Hammack- never heard of him, right? I love his videos as he dissects the physics and chemistry of how things work. Nothing fancy or gimmicky. Just good ol' experimentation, acute observation, rational deduction, and contagious curiosity.
He does one of his best jobs (my opinion) with Michael Faraday's The Chemical History of a Candle. Can't get much better binge-watching than the videos listed below- poetic language, simple and elegant demos, and a common phenomenon, almost always ignored, yet relevatory in its own right about science, the knowable underpinnings of the physical world, and the critical interplay among insightful observations, proper experimentation, and logical deduction. Get a bowl (or two) of popcorn, your favorite beverage(s), and sit back and enjoy.
