Igloos are known as a place of shelter during the cold winter months and actually do the trick under extreme circumstances. Some animals even make snow caves from time to time. Snow is a great insulator. The majority of fresh snow is composed of trapped air. The air molecules have a very hard time moving around and therefore have a hard time transferring heat. The heat stays where it is.

It is not unheard of for people to build a fire inside a large igloo too. According to an article I read online, with the help of an oil lamp, an igloo can raise the temperature by 40 degrees. Which is not as good as your house, but is much better than standing in the cold with no shelter at all. The igloo also protects you from the wind and keeps in body heat. To make a great igloo you need the right kind of snow, the fluffy and powdery snow won’t do. You want to pack the snow as tightly as possible.

Making an igloo can be a long process. First make numerous blocks out of snow and then layer them on top of each other in a circular fashion. Each layer should get smaller with height and turn slightly inward. The entrance should contain a ninety-degree angle. Next pack loose snow all over the igloo, especially in between blocks and crevices. Last but certainly not least don’t forget to add ventilation holes at the top of the igloo.

If you don’t have any fresh snow or cold temperatures you can always make an igloo out of milk jugs or marshmallows and toothpicks. If you decide to give it a try, email me a picture at aschilling@ktab.tv.
