It also comes up in STEM education content. For example, industrial dust explosions could be a good illustration of several principles (including the importance of surface to volume ratio), but... there are potential downsides to using it. More generally, STEM education remains innocuous only as long as it pervasively fails. If that ever changes, society will have some issues to decide. And not a great track record of handling similar ones. Even a simple matrix of "what do you get when you mix one common household material with another" has some "seriously: don't do that" nodes.
