Although it resembles a film you saw in elementary school, this 10-minute clip on how to build an igloo is entertaining and informative. The narrator runs through the basic history of igloos and shows how Eskimos create one using nothing more than snow and a knife.
I didn’t realize the difficulty in creating the spiral pattern with the snow blocks. Building one takes true skill. With winter upon us, could this be a project for your backyard?
