https://www.britannica.com/video/185632/formation-sand-quartz-role-processes-weathering-grains highlights of this weird video on how quartz becomes sand:
- the "everyday examples" of using sand are making sand castles (sure), keeping time with an hourglass (I guess if you're literally Jafar), and fracking (???)
- comparing quartz chemical bonds (strong) to orthoclase and olivine (weaker): "kind of like how a relationship forged in the heat of passion might not be as stable as deep bond developed over time" did...did something happen to this narrator?
@ingrid In defense of keeping time with an hourglass: dentists give those out to (at least) kids so I end up doing it a few times a day.
