Fluorine: It tastes like burning

This is the first I've seen of Dr. Martyn Poliakoff's Periodic Table of Videos but it's a good one. Each video is about an element, and this one focuses on Fluorine, one of those non-heavy elements that you still don't see very much of because of its extreme reactivity. That reactivity is on display in this as they use it to burn through steel wool and charcoal -- just by squirting it at them, even in cold, liquid form.

Unlike most chemistry, this video comes with a moral: don't mess with fluorine.
