Video of the Day: Igloos- Why do they work?
So you probably know what an igloo is, its shelter build from densely packed snow (the igloo design is mostly attributed to the Inuit people). Why would you build a shelter from snow-ice? Ice is cold therefore an ice shelter should also be cold should it not? Well no, aside from the obvious benefit of keeping new falling snow and winds off of you the densely packed snow is a pretty good insulator so good that if built properly an igloo can be heated quite efficiently just by your own body heat. Check out the video below for a greater understanding.
