Check out our Patreon page: full lesson: July 26, 1943, Los Angeles was blanketed by a thick gas that stung peoples eyes and blocked out the Sun. Panicked residents believed their city had been attacked using chemical warfare. But the cloud wasnt an act of war. It was smog. So what is this thick gray haze actually made of? And why does it affect some cities and not others? Kim Preshoff details the science behind smog. Lesson by Kim Preshoff, directed by Juan M. Urbina Studios.
