Aug. 2nd, 2003 07:46 amQ: What causes fog?
According to recent experiments, a half pint of Jim Beam generates a pretty good fog. Another cause of fog is water condensation. Fog occurs when water vapor in the air begins to form into tiny droplets of liquid. At any given time, the air can hold only a certain amount of water vapor at a particular temperature. This is called its holding capacity. When the amount of water vapor exceeds the holding capacity, it condenses into fog. Holding capacity increases when temperature rises--that's why sunshine is said to "burn off" fog. If you want to get technical, according to international definition, fog is any condensation that reduces visibility to less than one kilometer (3,281 feet).
Fact of the Day
Avoid keeping chocolate too cold. If stored at temperatures below 55 degrees F, chocolate will sweat when brought to room temperature too quickly.
