Harry Potter’s fabled invisibility cloak is slowly becoming a reality. The British startup Invisibility Shield reported the creation of a material, behind which any objects become invisible.
To earn money for further research, the company has placed its invention on Kickstarter. To become the owner of a rectangular-shaped shield of the miracle material measuring 90 x 60 cm is possible for $ 400.
One of its main advantages – the ability to work without a power source. And yet the technology used here – just a clever optical trick, a kind of funny engineering. The shield uses a precision matrix of lenses to direct most of the light reflected from the object away from the observer. Thus, the object hidden behind the shield becomes virtually invisible.
