Researchers at the University of Texas have taken us one step closer to invisibility. A team created a 0.15mm-thin sheet that can hide a 7-inch tall cylinder...from microwaves. Yeah, that's not as useful as hiding something from visible light, but it's still super awesome cool. What's even more interesting is that the invisibility "cloak" is made from copper and polycarbonate, and as ExtremeTech explains, that's much different from the metamaterials (materials with properties that can’t be found in nature) used in previously announced invisibility cloaks.
