你敢信吗？最冷的雪，反而能让你暖到发烫。从北极熊到因纽特人，千年来都在用“冰屋”对抗极寒。这背后藏着怎样的物理奇迹？
There are few things in this world that will keep you as warm as snow, which at first seems impossible.
How can something that is frozen keep you warm?
But countless animals burrow into the snow to keep warm, and Inuits have been making igloos for centuries.
The question is, how can frozen water actually keep you warm?
Okay, full disclosure, I've never actually built an igloo before.
And from everything that I'm reading online, they actually seem pretty difficult to build.
So, what I'm building right now is actually a Quincy, which is slightly different.
A true igloo is made by stacking snow blocks that are cut from the existing snow pack.
The blocks are stacked in an upward spiral, forming the walls of an igloo.
The key to the whole structure.
