I first read about metallic microlattices on the BBC website last week.

The substance is believed to be the worlds lightest material. It is 100 times lighter than Styrofoam and has a density of 0.9mg / cm³ – less than what were the worlds lightest materials, silica aerogels.

The sustance is 99.99% air, 0.01% solid.

The walls are 100 times thinner than a human hair.

Read more about this unusale material here and here.
