Heya, Steve. Good to see you back again.
The part of this video that I think I most appreciate is the actual look at the guts of a piezo electric safety lighter. I've used them for a long time and never quite been sure how they work on the inside.
I also appreciate Steve's comments on quarts 'healing crystals' around 1:40. "Don't know if you take it orally or..."
And then we get into the fact that piezoelectricity is dependent on the electronegativity differences in a quart crystal (admittedly simplified in Steve's peanut-butter-jar model). I'm totally duplicating this post for my chem blog because of that explanation.
