So all these efforts either hide things in wavelengths longer than we can see - radio, microwaves and a bit of infrared - or hide objects so small we can't see them.

BBC: Invisibility cloaks: Will we ever really have them?

While the scientific babble may not mean much to you, the long and short of it is that this discovery could "lead to further breakthroughs in invisibility cloaks, which could hide objects from the human eye" and make escaping your troubles quite a bit easier.

"By using natural crystals for the first time, rather than artificial metamaterials, we have been able to scale up the size of the cloak and can hide larger objects, thousands of times bigger than the wavelength of the light, " said Shuang Zhang, the University of Birmingham physicist who led the research.

BBC: Invisibility cloaking benefits from crystal-clear idea

The work in Nature Communications can hide centimetre-sized objects, limited only by the calcite crystal's size.

Tiny carbon tubes can be used to hide three-dimensional objects from view, according to a team of researchers.
