Invisibility Cloak Enters The Real World
In the past researchers have only been able to "cloak" microscopic objects using extremely complicated physics and so-called meta-materials made on a tiny scale. But a new study at the University of Birmingham has taken a massive step forward by making a paper clip invisible – an object thousands of times bigger than previous experiments. The research works by using a naturally forming crystal called calcite which has extraordinary light bending abilities. By placing the crystals over an object it "bounces" light around it rendering it totally invisible to the naked eye
