    I just love the stuff from Things I Won't Work With. It works great with somebody describing the chemical under discussed. Not everyone was obsessed with the idea of explosives in highschool and can look at AAs formula on a page of text and go "holy hell, that is a scary number of nitrogens".

      Fluorine maybe incredibly dangerous on its own and in several chemical compounds. But so Chlorine, and it’s one of the ingredients in Salt.

    These people would come across a beautiful flower on the edge of a calm stream and think... "yea but can it be weaponized?" That violent state of mind should probably be studied with as much enthusiasm too no? because it's producing a being so toxic it has a violent reaction to everything it touches. Nature fights back in its own unique way though. Hopefully it continues to hide it's secrets for a more deserving species on this planet that isn't hell bent on destroying itself as a means of survival. Love your channel though.
