Well, it certainly isn’t made of sidewalk.

Sidewalk chalk isn’t made of chalk anymore?
TIL: It’s made of calcium sulfate, i.e. gypsum, the same stuff that goes into drywall, as opposed to calcium carbonate, i.e. rock chalk.

Unless your sidewalks are made of gypsum.

If there are, they won’t be for very long.

No wonder it doesn’t taste good anymore.

Wow, so 20,000 people read this?
Lemmy’s more popular than I thought.

Yeah… that’s really not in the 1 in 10k catagory. Not even the 1 in 10 catagory.

i pretty sure those numbers are in reverse, at least if i understand you correctly. Its 1 in 10(lots of ppl know) then 1 in 10(less ppl know) and so on.

Nope. Not reversed. The guy I responded to thinks that almost everyone (9,999 out of 10,000) knows sidewalk chalk isn’t made out of chalk. I’m saying it’s not even as common as 9 out of 10 know that sidewalk chalk isn’t made out of chalk.
In fact, I’d say the odds are more like 1 out of 2, at best. Possibly even that more people would give the wrong answer than the right one.

I would say it’s probably a lot less than ten thousand - I doubt this is something “everybody knows”
