In early 2011, Toby Schaedler and his team at HRL Laboratories invented a "metallic microlattice," so named for it's composition & structure, that is 100x lighter than Styrofoam. It is also lighter than aerogels and carbon nanotubes.

The material is 99.99% air, and the rest is mainly nickel alloy. Photographs show it sitting on top of a dandelion without crushing a single wisp.

The metallic lattice was devloped for DARPA (Defense Advanced Research Projects Agency) for its potential use in everything from shock absorption to batteries to insulation.
