This video demonstrates an "invisibility cloak" that can make objects beneath it disappear. Scientist Ali Aliev at the University of Texas in Dallas is working on a technology that uses thin threads of carbon nanotubes that, when heated rapidly, makes it look like the objects under the tubing disappear. This technique uses the "mirage effect." When the carbon tubes get extremely hot, their surface bends light around it and "hides" the object. This big change in temperature over a small distance bends light rays so they're sent towards the eye tricking the brain into thinking the rods are invisible. Experts say this technology can be used for military tanks and planes with temperature-sensitive plates.
