Artic Survival Tips for the Young Explorer

The "blue" in the ice of a moulin indicates ice safe to drink. The white ice (at the arctic sea shore) contains salt and in a survival situation is not safe to drink. The blue ice is aged and the salt content is apparently gone from it. Melt it in your hand and drop the drops into your mouth. If you eat it as ice, it will help lower your body's core temperature which can hasten freezing to death.
