I just about read a neat
bar trick over at
You Look Like I Need a Drink.
Scenario: You are at a bar, and because there is a lack of coasters, your cold frothy beverage is placed on a napkin
The inherent problem with this oft used coaster replacement is that as the condensation forms on the outside of your glass, it eventually follows the laws of gravity and inevitably, the napkin ends up stuck to the bottom of your glass as you are toasting to your friends.
I won't spoil the solution... head on over to
