Ingenious building material that shapeshifts in response to rain
from Fast Company
When Chao Chen had to conduct a materials study during his second term at the Royal College of Art, he found inspiration while walking through London's Hyde Park on a rainy day. Picking up a pine cone, he noticed that it reacted to water by closing its outer shell. Now, he has developed a building material, based on the pine cone's anatomy, that can shapeshift in response to weather.
