Re: History Channel Makes a startling discovery.

Although I agree with the OP that the Discover Channel screwed up this one there is an interesting phenomena where you can indeed superheat (heat water above it's boiling point at the current pressure) purified or distilled water in a glass or smooth container given rare circumstances.

Given water without pre-existing bubbles and pure enough that the nucleation threshold is homogeneous throughout the fluid, the first and primary nucleation moment (think the formulation of the very first steam bubble) can require more energy than there is available at the boiling point. Once the first bubble forms and physically disturbs the superheated water it cascades to boiling.

Gotta love science!

But I'm pretty sure that the Discovery Channel is NOT in any way referring to this phenomena.
