    If we use chlorine trifluoride as jet fuel it can melt steel beams

  • Shut Up, Sprinkles!

    Why are lesser-known toxic paints like cadmiums and cobalts toxic?

    Or, how are chemical compounds transformed to be used as pigments in paint?

    Or...why are fluorescent colors not lightfast?

    Honestly I just want to see an episode about paint and pigments—the chemistry is absolutely fascinating.

    Long story short i was in a chemistry class and we were writing down some covalent molecules and all the other students wrote really simple every day molecules and I wrote chlorine trifluoride because ironically last night I watched this video and this was the conversation my teacher had.

    Teacher: "Oh wow chlorine trifluoride, that's a pretty dangerous chemical"

    Me: "oh I know. I'm aware."

    Teacher: "you know? How?"

    Me: "I have my ways."

    You forgot about Dioxygen Difluoride, more commonly known as FOOF due to its... _interesting_... properties, and the absolute madman who decided to react it with half of the chemicals in this list (_and more. _*_what?_*), A.G. Streng.

    somebody please help me find this video I once saw of a chemical reaction between 2 or 3 household thingy's in a bottle. It wasn't mentos and coke or anything with baking soda , and it wasn't a good ol works bomb. It was like the guy added the second or 3rd thing and the guy stood back and there was a firey violent reaction. Dammit I forget.
