Building an igloo takes a lot of time and focus; sometimes you can be out building for 5 hours, depending on any interior designs the builder wanted to add.

Need to Know
- How do you build the ceiling to make sure it doesn't collapse?
- If you don't have thick, compact snow, how do you make sure the structure is sound/stable?
- Where can you get a snow block mold?
- Why is the crescent shape the best option for ventilation?
- How can you have a fire inside the igloo?
- What is the most effective survival shelter when stuck out in the snow?
- How igloos don't melt with all the CO2 inside from people living in it
Take your time when building closer to the top; you need a really solid, firm base if the roof is going to stay intact. Smooth snow over all the cracks and making sure it is smooth and completely compact. WikiHow; How to Build an Igloo
It will take a lot longer to build an igloo with powdery snow, but you can mix the snow with a very small amount of water until you can press the snow very compactly into the mold. If the snow is not packing enough to where you feel the roof will be stable, you will have to find something you can put over the top and cover with snow, or you can spray water on the snow to create a solid ice layer.

The crescent shape is the most effective because it is big enough to allow CO2 to escape without letting out a lot of heat. They also won't weaken the base like a square or circle would. WikiHow; How to Build an Igloo
An igloo is absolutely not the most effective survival shelter if you're stuck in the snow; a snow cave would be your best bet. WikiHow; How to Build an Igloo
The heat from your breathing and even just your body heat do warm the igloo, but since the snow itself is cold as well as the air outside, the snow will solidify and make the structure stronger. WikiHow; How to Build an Igloo
Figurative Language
- Spraying water on the outside of the igloo gives it a shell of ice which makes the igloo more sturdy. You do not need to spray the inside, as your breath is hot enough to melt the inside a tiny bit, but then it refreezes and creates the ice shell there.
