Memory metal paperclip

Shape-memory alloys flip back and forth between two solid crystalline forms called Austenite and Martensite. At lower temperatures, they take the form of Martensite, which is relatively soft, plastic, and easy to shape; at a (very specific) higher temperature, they transform into Austenite, which is a harder material and much more difficult to deform. Let’s…

Boeing unveils metal that is ‘slightly lighter than air’

Boeing claims to have created the worlds lightest metal, stating how the breakthrough could have major implications for aircraft and automotive fuel efficiency. The material is composed of a microlattice structure made of 99.99% air which makes it light enough to balance on top of a dandelion. Watch the video here: Boeing unveils metal that is…
