World's Most Expensive Quilt: Arctic Bird Feathers

Imagine a super-warm, super-light blanket made from the soft feathers of Arctic ducks.

These ducks, called eider ducks, have special feathers called eiderdown.

They collect these feathers from their chests to build their nests.

The feathers are amazing because they are hydrophobic, so they repel water, keeping the ducks warm and dry.

Only a small amount of this special down is collected each year, making it very rare.

Because it's so rare and effective at keeping people warm, one quilt made from this material can cost around Rs 12 lakh.
