Liquid light bender proposed

Tiny nanoparticles dispersed in fluid may hide objects

Tiny silver-coated rust particles suspended in water may give the fluid light-bending superpowers, physicists suggest in a paper to appear in Physical Review Letters.

Simulations with the proposed fluid system find that it could disguise objects from many wavelengths of visible light, lead author Jiping Huang of Fudan University in Shanghai and colleagues report.
