The Lightest Metal Ever

Aerospace giant Boeing has released a video showcasing the lightest metal structure ever, which is also one of the lightest materials known to science, called Microlattice. The entire structure is 99.99% air and is comparable to the hollow honeycomb architecture of bone. The structure is composed of a network of super thin, hollow struts. The struts are around 100 micrometers in diameter and have walls just 100 nanometers thick. It's this design that makes Microlattice 10 times lighter than Styrofoam. However, despite it being insanely light, it is also extremely strong.If planes made from this material we can fly more faster because this material is the lightest...And this mean burn less fuel...
