Oh. Yeah. Good point. Obviously I wasn't thinking too hard about this. Thank you.

Wait, so they put the glass is a liquid theory into school curriculum and it was this easy to test?

I don't recall that in my own school curriculum. I'll be thinking about whether to reduce my trust for my own schooling experience. It can't go much further down after reading John Taylor Gatto, but if the remaining trust that is there is unfounded, I might as well kill it, too.
