Why do sterling objects fog up when I blow on them

Asked Jan 12, 2013
When there is a temperature difference between the object and your warm breath, the air condenses when it comes in contact and produces the fog. It's the same principle as windows fogging when it's warm inside and cold outside. It happens with everything, it's just more visible in objects that reflect light.
