Going Invisible-The Technology Continues

A team from the University of Dallas in Texas have created an invisibility cloak by electrically stimulating a sheet of carbon nanotubes The  tubes heated up so quickly to a high temperature  and this steep temperature gradient  between the sheet and its surrounding area caused visible light rays to bend in the same way it does just above a very hot road in the desert. This is analogous to the mirage effect whereby light from the sky gets redirected over the surface of the hot road, making it look watery. The mirage tends to hide features behind it.

This discovery gave best results underwater when tested.
