Shape-Shifting Crystals Can Transform Into Any 3D Shape

Scientists from the United States Air Force Research Lab have developed an new transparent material (a new type of a liquid crystal elastomer (LCE)) that can be programmed to form any shape. Snip from Popular Mechanics:

The sheet expands upwards, morphing into a pre-programmed 3d shape that’s tough yet springy (like a rubber-band) and more than a hundred times thicker than before. For a study out in Science today, the material’s creators programmed it to transform into a mini quartet of mountains—and as it forms the four peaks, it lifts a slate of glass 175 times its own weight.

Support arts in education. Many studies have concluded that curricular and extracurricular art studies and activities help keep high risk drop out students in school. There is a 4% drop out rate of low income students with high participation versus a 22% drop out rate with low participation. Support our Express Yourself Campaign.
