What Causes the ‘Fog’ in a Refrigerator?

Fog in the fridge is like breath on a window, it's water turning from gas to liquid. When you open the fridge, warm air goes inside and meets cold air. The warm air holds lots of water vapor, but when it gets cold, that vapor turns into tiny drops of water, making fog.
