Today you learn about the surprising reason why you shouldn't take out your phone in class.

Tiny Cities made up almost entirely of

bookstores and a ridiculously dangerous chemical that can make anything burst

into flames on contact. Let's set us for some curiosity.

Cody, do you want to learn about a stupidly dangerous chemical?

Do I? When would I not?

This is the best way to start your day.

Absolutely.

Today we're taking a deep dive into a liquid chemical that's so corrosive it can make

practically anything burst into flames on contact. It's called chlorine trifloride

and it should go straight to the top of your list of things to avoid at all costs.

Don't worry about running into it by accident though.

The compound has been banned under the Chemical Weapons Convention.

Chlorine Trifloride is even more reactive than fluorine, which is so reactive that it turns water into

oxygen on contact. That makes it pretty much impossible to store in solution, and that's why

scientists in the 1930s set out to find

something that's easier to handle but just as reactive. They isolated the compound

chlorine trifloride which was liquid and even more reactive than fluorine. But it might be a bit too

reactive. Springling this chemical on virtually anything will start a fire that you can't
