The idea of turning invisible could be closer to 'science fact' than 'science fiction'.<br /><br />Researchers at the University of Texas have for the first time used an invisibility cloak to make a three-dimensional object.<br /><br />One cloaking technique uses so-called meta-materials to redirect light, creating 2-dimensional invisibility; another uses a heat panel to create a mirage effect, bending the light to trick the eye.<br /><br />The latest advance uses plasmonic meta-materials to cancel all reflected light. No reflection means the object disappears into 3-dimensional invisibility.<br /><br />Al Jazeera's Jonah Hull reports from London.
