A view friends had an idea to build an igloo. They are from Canada (at least most of them) and while everybody in Canada is working hard to breakdown stereotypes we decided to push back a little and actually build an igloo.
You don't need much, a good amount of sticky snow, a mold to create the building blocks, a saw to mold the blocks when needed and a general idea of how to build it up (the walls should continuiously slope inward for the dome shape).
We started by using the full blocks out of the mold for the first two layers, then moved to 2/3 for layer 3 and 4 and then moved to 1/3 for the final layer and roof. We continuiously enforced the joints by creating as much touching points between the blocks and filling up any spaces that were left.
With 4 guys it took us about 2 hours for our first attempt and it actually worked. Here is a link to the photos...
