Want a boring explanation?

This is a common issue that those involved in generating high vacuum
levels in chambers have to deal with.

Residual water vapor molecules are the most significant gas load in
creating a high vacuum state. They are attracted to and tend to "stick"
to the chamber walls and any other surfaces within the vacuum chamber.
This phenomena is called the "Van der Waals" effect. Molecules tend to
attract by this weak force.

In vacuum chambers, additional energy is imparted to the clinging water
vapor molecules in the form of high powered, radiant heat sources or by
ion bombardment from a ion source or simple "glow discharge" bar
arrangement. The added energy from these sources cause the "clinging"
molecules to break free and be captured in the high vacuum pumping system.

Told you it was boring.







Well, *that* explains the problem I had with my lawnmower earlier this
year.
