When I was younger, I used to notice how all my cold carbonated drinks would have bubbles on the inside of the glass while having water drops on the outside of the glass. With the great deduction skills of a seven year old I thought that the liquids just permeated the glass and exchanged places with the air.
Then I went to class and got schooled. Itís still fun to think about.
Stemless wine glass with some sprite or something in it. I forget.
