Whatever you might think of Edward Snowden, you can keep to yourself; this is a booze blog, after all. But in reading a recent New York Times story about his flight from Hong Kong, I found a funny tidbit.
You see, when a group of lawyers arrived to advise Snowden in Hong Kong, he asked them to stash their phones in the refrigerator. According to Adam Harvey, a designer specializing in countersurveillance, it seems that the materials in the fridge walls serve as a Faraday cage, a space that can disrupt radio communication.
For the drinker with something to hide, however, there’s a better solution:
Another household object that functions similarly, Mr. Harvey has learned through his research into cellphone data transmission, is a stainless steel martini shaker.
“It’s a perfect Faraday cage – it will block all radio signals unless you decide you need to pour yourself a martini,” he said. Although this sounds like a plot point in a James Bond movie, Mr. Harvey has actually done extensive tests on the shaker in the process of developing a surveillance-blocking cellphone case called the OFF Pocket.
Now that’s cool. Most of serious cocktail geeks probably have four of those damn, otherwise-useless things cluttering our barware. At least they’re useful for something.
