Portable Cloaking Device
Researchers at the Karlsruhe Institute of Technology in Germany has created a device that can demonstrate invisibility anywhere. KIT researchers use a hollow metal cylinder that has a coat of acrylic paint on it. The paint will help diffuse the light around the object. Then the metal tube will be placed in a block that gives the illusion that the object is gone. The block is made of a silicon-based organic polymer (PDMS) that has titanium dioxide nanoparticles used to scatter light waves and to slow them down.
