Bird's Water-Holding Feathers Inspire Innovative Bottle Design
The intricate feathers of the Namaqua sandgrouse, an African bird, have inspired a team of American researchers to develop innovative products such as water bottles that hold water to prevent annoying sloshing around, and netting which can collect and retain water from fog. The feathers of the desert-dwelling sandgrouse can soak up water like a sponge and keep it stored even while the bird is flying 40 mph. The study authors hope the new discovery could lead to bio-inspired creations and influence future engineering designs that require controlled absorption, secure retention, and the easy release of liquids.
