frosty glass

[calz]

the other night i was having a bud, watching the game, when i noticed a wierd thing. i had put my cold beer bottle down on the glass-topped coffee table in my lounge, and when i picked it up again a ring of condensation had formed beneath the bottle, but on the UNDERSIDE of the table top. HOW and WHY does this happen?

thin table?

The beer made the glass cold enough for humidity in the air to condense on it.
