Lightest Metal Ever Made is 99.99% Air
Added Oct 12, 2015 | Rate View top rated
Sophia Yang, research scientist at HRL Laboratories (a corporate research-and-development laboratory owned by The Boeing Company and General Motors), describes the development of a groundbreaking microlattice. At 99.99% air, it is the lightest metal ever made and is light enough to balance on top of a dandelion, while its structure makes it strong. The mircolattice is a 3D open cellular polymer structure and is comparable to a bone structure, where the outside of the bone is rigid and the inside is mostly hollow. Strength and record-breaking lightness make it a potential metal for future planes and vehicles.

You know, this stuff would be great to replace foam in car or furniture upholstery! It flexes back just like foam, it seems, and I'd bet it doesn't break down nearly as fast when a rather heavy wide butt sits on it repeatedly (ever seen the side bolsters on the seat of a fat guy's car? Smashed flat, along with the torso side bolster next to the car door. (not knocking overweight people here, but car seats are not made to stand up to 250 plus pound people. In aircraft it might even save some weight, and I doubt it's as flammable as foam is either (remember that steel wool is a great fire, and so is magnesium) Surprised nobody else commented on this, but I'd think SOMEONE would be interested in it. Hell, give me a way to mold it or cut it to the dimensions of my rally car seats and I'll test it myself! Dave

This video is poorly named. "Lightest metal ever made" implys some new metal. It's a new structure, not a new metal. Not to mention that the video is more advertisement/P­R than technical information, and so inappropriate for this publication, IMO.
