Pat sent this to me:=============================
I was taking a ground school class for private pilots. During the
session on weather, the instructor wanted to discuss the concept
of sublimation, the act of going from a gas to a solid skipping
the intermediate liquid stage. He gave as an example water vapor
in the air condensing on a windshield to form ice.
Wanting to see if the class had understood the concept, the
instructor asked if anyone could provide an example of something
that went straight from a solid to a gas. He was expecting "dry
ice'' as the answer.
One of the students blurted out, "Burritos."
