PRINCETON, N.J., March 25 (UPI) -- A team of researchers at Princeton University recently poured out perfectly good whiskey and let it evaporate. The loss wasn't a total waste, however, as it may ultimately lead to a new type of industrial coating.
The experiment was inspired by the curiosity of photographer Ernie Button who noticed the last few drops of whiskey, when left in a clear glass, left behind unique residues. When lit from beneath using different colored lights, the whiskey glass and patterned residues made for dramatic photography.
