Going Drinking? Don't Forget Your Laser
Researchers in the United Kingdom have worked out a way to use lasers to determine the authenticity of whiskey, which, depending on its age, brand and even cask, scatters laser beams differently.
The good news is that researchers still haven't come up with a means of determining that you're not really here in town at a convention of Doctors Without Borders, and that the moment you saw her from across the bar, you didn't really think she was "the one." So... spend a little more on your whiskey, but ride the Doctors line all the way home, if it's working for you.
