How Do Ducks Stay Dry?

The video explores the unique properties of duck feathers, which are hydrophobic and structured to trap air pockets, providing insulation and reducing drag. A 2021 study revealed that multiple feather layers enhance water resistance by creating a maze-like barrier. Synthetic feathers mimicking this structure could have practical applications, such as reducing drag on boats. Ducks have adapted to have the optimal number of feather layers for their diving depth, showcasing an intriguing example of natural adaptation.
