Scientists Develop World's Lightest Metal, 100x Lighter than Styrofoam

"This, we assure you, is a real photograph. Researchers at the University of California Irvine have developed a material that is as strong as metal but 100 times lighter than Styrofoam. The material is constructed from a micro-lattice of nickel phosphorous tubes that is 99.9% air. The tubes are hollow and have walls 1,000 times thinner than a human hair yet have the strength of metal with the added benefit of being ultra resistant to strain. Researchers believe this new metal could be used to make light weight batteries that could eventually bring down the weight, and increase the efficiency, of green vehicles and use less material in the process."
