This metal is light enough to be balanced on top of a dandelion, because it consists of the air for 99.99% and it’s 100 times lighter than Styrofoam, Joinfo.ua reports with the reference to Geek.com.
Researchers from HRL Laboratories of Boeing were able to achieve this innovation by creating a metallic microlattice structure, which researchers explain as “a lattice of interconnected hollow tubes with a wall thickness of 100 nanometers, 1,000 times thinner than a human hair.”
The microlattice gets its strength from this “open cell” structure, which mirrors that of human bones. It’s solid on the outside, but filled with a light marrow on the inside. The microlattice’s “marrow” is a small network of interconnected tubes, which prevents the structure from breaking.
