Here's an igloo I built with my friends using small crates and shovels and a watering can. Because of the powdery texture of the rare Irish snow, we had to make blocks by compacting snow into crates, then pour water over them to freeze them into solid blocks. Then we built a spiraling circle coming in on itself and used a slushy water/snow mix to finish the roof. Like anything worth doing, it took 20 man hours.
We have a be nice policy.
Please be positive and constructive.
