Building an igloo in 20x time-lapse. Ok, this is not a perfect igloo, but is comfy enough to hide from blizzard or just to play with your kids. It was filmed on Jan 16. 2013 in Zagreb, when a blizzard brought 70 cm of snow in a single day. For the mold we used a plastic box, the kind you can find in any home-store. Do not pun snow too much into the box - it has to be hard just enough not to crumble apart when you handle the block. Making the blocks too hard would be just a waste of energy and time, without much benefit.
