I meant to say that :
How is it possible that a bottle with the coaster joint? (See the pictures)
mathslover (mathslover):
There was only water between them
OpenStudy (experimentx):
did you heat it?
OpenStudy (anonymous):
The water around the bottom of the glass creates a hermetic seal around the bottom edge of the glass. The water has enough surface tension to prevent air from getting in. When the glass is lifted, a vacuum is created between the bottom of the glass and the coaster. This creates suction, and it can be enough to lift the coaster.
