The U.S. military is backing the development  of camouflage fabrics that could one day make their soldiers completely  invisible, it has been claimed.

The so-called 'Quantum Stealth' camouflage  material is said to render its wearers completely invisible by bending light  waves around them.

Its makers claim the material, which is in  effect similar to the invisibility cloak worn by Harry Potter, can even fool  night-vision goggles.
