Fun Fact: How bees cool the hive

Fun Fact: Bees air condition their hive the same way we do with water evaporation.

Bees will go out and bring back water,

Then they coat as a thin layer on the rims and caps of the cells.

Next, fanning bees will position themselves in a line up and will fan their wings.

With all the bees fanning together their combine efforts make a great air flow in the hive. 

When they fan like this it's called "stationary flying"

This video is of bees doing stationary flying at the hive entrance to pull hot air out and push cool air in.
