The penchant for invisibility

A cloak that can make objects go invisible has been developed by German scientists. The Harry Porter kind of invisibility cloak can conceal objects and is handy enough to carry around.
The object that is to be concealed is placed in a metallic cylinder which is coated with acrylic paint. Then the cloak uses diffused scattered light which acts like frosted window panes, it lets light in but hides the source of light. By scattered light, the material declines the propagation speed of light waves through the source.
The light then rushes to make up for the longer path length surrounding the hidden object.
The cloak cannot hide humans or objects that are in huge size but can make small objects go invisible.
