Wetness-defying water | Science Blog:
"The textbooks say that water readily comes together with other water, open arms of hydrogen clasping oxygen attached to other OH molecules. This is the very definition of 'wetness.' But scientists at Pacific Northwest National Laboratory have observed a first: a single layer of water--ice grown on a platinum wafer--that gives the cold shoulder to subsequent layers of ice that come into contact with it...They found that the first single layer of water, or monolayer, wetted the platinum surface as they had expected but "that subsequent layers did not wet the first layer," Kimmel said. "In other words, the first layer of water is hydrophobic.""


  1. How could you adjust the properties of water with PLATINUM to make it hydrophobic? That's... weird.

  2. Exactly...though it's probably just the result of e- density shifting...but it's still just weird.
