Reading what Milo wrote brought back a mental flash of one of those educational programs I saw years and years ago. The narrator, someone famous I've long forgotten, showed the viewing audience a big metal ball--I've forgotten its size, but it may have been between the size of a softball and a basketball. Anyway, he said that if this metal ball were the earth--then he blew his breath on the ball--that the film of moisture he'd just blown would be the depth of the oceans. I thought that was pretty cool.

Breath regards,
