Are you a nervous flyer? Do you do everything in your power not to flap your arms uncontrollably to make sure you stay airborne? Well, you might not want to consider that planes of the future could have elements made from microlattice – a metal developed for Boeing that’s 100 times lighter than styrofoam.

You might also be a touch alarmed to hear the experts explain that the metal is 99.9% air. However, it may give you a little more confidence to learn that the inspiration for the design comes from the hardiest of body parts: bone.

You can even put folders inside other folders. For instance, you could create a folder called “vacation photos” and put it inside a “memories” folder. Neat and tidy, just the way we like it.

Get started
