Four years ago my then-third-grader was given a reading comprehension assignment that purported to be about processed foods, and had as one of its facts that Wendy's chili contained sand. I made a great "is this source reliable?" assignment out of it for him, but that was pre-chatgpt, when

I could just say "that author is trying to mislead you, or that author is wrong" - now I would have to say "or maybe that author was lied to by a lie machine", ugh

This is actually technically true — the ingredients listed for chili con carne include a "flavor enhancer" with sub-ingredient silicon dioxide, which is what sand is. Idk where food-grade SiO2 comes from (probably not, like, BEACH sand) but it's a verifiable fact that Wendy's chili has sand in it.
