Haha, this is great. A kiwi student who visited his girlfriend in Canada during winter break ended up building an igloo out of 500 or so coloured water bricks in her family’s backyard, because her mum wanted one. It took many empty milk cartons, over 150 hours and tenacity against the subzero temperature. Well, at least it looks spiffy. If he’s revisiting the family next winter, we suggest using bricks straight from juice cartons, because we’re greedy that way.
