With a density of 0.9 mg/cc, the world’s lightest material is put forward by researchers from UC Irvine, HRL Laboratories and the California Institute of Technology. The material features a unique “micro-lattice” cellular architecture, 99.99% of which is air and only 0.01 percent is solid metal. Thus it weighs incredibly light, even about one hundred times lighter than Styrofoam, and can stand safely on the top of dandelion. Even so, the material still comes with a good mechanical behavior, including complete recovery from compression exceeding 50 percent strain and high energy absorption.
