Graphene, which is the same as the flakes from your pencil when you write, could be the wonder material of the new millennium.A few years ago, researchers discovered its electrical properties, making one-micron sheets of the stuff ideal for tiny computerized devices. Now a new study reveals that graphene may also be one of the strongest materials known to humans. It has a breaking strength of 55 newtons per meter. For non-newton meter readers, that means if you had a sheet of graphene that was the thickness of typical plastic wrap, it could support the weight of a 4400 lb car before breaking. Just to make things even more supercool, graphene is also transparent. Yes, ultra-thin, invisible body armor for the future!
