From the page: "Researchers directing a special type of light at metal poked with holes in irregular patterns recently discovered that all the light behaved like a liquid and fell across the metal to find its way through the escape holes. That means the light was acting pretty weird. Picture shining a flashlight at your kitchen colander. While some of the light from the flashlight will travel through its holes, the solid part of the colander will keep much of the light from shining through. In contrast, experiments described in the March 28 issue of the journal Nature demonstrated that terahertz radiation--a low-frequency light on the electromagnetic spectrum located between microwaves and mid-infrared regions--traveled around a thin sheet of metal, through patterned holes, and all of it came out the other side. Experts sometimes refer to this radiation as T-rays. "

Watery light isn't exactly some newfangled discovery. Scientists studying Quantum Physics have known for a long while that photons can act as both a wave and [or?] a particle. Here's a link on wave-particle duality and another on the double slit experiment.
