Researchers from the University of Dallas in Texas have hijacked one of nature’s most intriguing phenomena — the mirage — to make an invisibility cloak. It can hide objects from view, works best underwater and even has a near-instant on/off switch.
To understand how it works, you need to first grasp the basics of the mirage effect. This unusual experience, sometimes seen in the desert or on hot roads during the summer, can trick your brain into seeing objects that aren’t really there.
