When you think about it igloos shouldn’t work. A little hut made out of ice and snow in a very cold place that stays warm? But they do! Here’s how
Igloos are built out of bricks of ice. Unlike solid ice, which is a poor insulator for heat, all the compressed snow has more air pockets, making it a perfect insulator. All the cool air in an igloo goes to the bottom part and stays there. This means the upper area of the igloo remains warm. The heat is generated from body heat of the humans inside the igloo itself. Sometimes a small fire is use for heat as well.
Mind blowing! Eskimo life is the best.
