    My 4th grade science teacher genuinely taught us that “blood is blue before it leaves your body and turns red due to oxidation from contacting the air”

      Even as a kid I thought that was stupid. If blood is blue in the body and only turns red when it touches oxygen, then why is it red in the water?

      I was told that’s only in the movies. In real life it would be blue.

      But then again I got a detention for arguing that the moon is visible during the day. The detention was because I pointed out to the window and said look, and she was embarrassed.

        The detention was because … she was embarrassed.

        Ohh yes, classic detention for proving the teacher wrong. There’s a depressing amount of teachers who rule by their ego instead of by science. It’s why I now consider my school discipline record as a source of pride instead of shame.

        We had the internet and a handful of us tried to contest it. She said “look at your textbooks, they clearly drew that blood from your arteries”
