A professor made a device that can make you invisible

John Howell, a physicist at the University of Rochester, invented the Rochester Cloak, an arrangement of lenses that bends light around the object in front of it. Later, he invented another optical cloaking device, which brings the same physics principles to scale. The whole thing costs $150 and is made with standard hardware store materials.
