A new material developed by Boeing is made of metal, but it’s so light it can balance delicately on top of a dandelion. The product, called microlattice, is 100 times lighter than styrofoam, according to Boeing, and is made with interconnected hollow tubes. Its structure is similar to that of a bone, in which the outside is rigid but the inside is mostly hollow, making it lightweight but not easily crushed.
