Physicists figured out the complex mathematical equations for making objects invisible by bending light around them last year.

The design calls for tiny metal needles to be fitted into a hairbrush-shaped cone at angles and lengths that would force light to pass around the cloak. This would make everything inside the cone appear to vanish because the light would no longer reflect off it.

This new design is the first for cloaking objects of any size in the range of light visible to humans.
