You’ve likely heard of or seen swordsmen who can expertly and accurately slice through all kinds of objects, but scientists are now taking precision-cutting to the next level of awesome.
Researchers at Arizona State University, in cooperation with colleagues at Youngstown State University, have perfected the subtle science of slicing water droplets in half. They detailed their exploits in a study just published in the online open-access journal PLoS ONE.
The scientists accomplished the feat using superhydrophobic (extremely water-resistant) knives and cutting surfaces. The knives were composed of polyethylene and zinc and dipped in solutions of silver nitrate and another superhydrophobic solution abbreviated HDFT (its systematic name is far too long to fit on one line). Cutting surfaces were simply composed of Teflon.
Even with their water-resistant knives and cutting boards, the researchers had to be incredibly meticulous when actually slicing the H2O. They delicately cut through water droplets…
