I don't know about you guys, but the second that I saw on screen that Harry Potter was able to use just a bit of cloth to make himself completely disappear, I knew that I wanted one too. Unfortunately for me, however, the invisibility cloak was totally fiction... Until now. That's right ladies and gentlemen, an invisibility cloak could be in the works.
Engineers have invented a flexible, stretchable material which could coat the next generation of stealth aircraft and missiles to hide them from radar detectors. The material, called meta-skin, traps radio or microwaves so they won't show up on radar detectors. This material has been created by engineers at Iowa State University here in the United States.
Current tests show that the cloak has been able to suppress seventy-five percent of radio waves. However, it is important to keep in mind that, unlike the cloak from the books and movies, this cloak won't make you truly invisible.
The material itself is made up of rows of rings with a radius of 2.5 mm and gaps of 1 mm, filled with a metal alloy that is liquid at room temperature called galinstan.
