In addition to the powered version of vodka invented by a St Petersburg professor I mention in my book, a Harvard professor has invented a vodka mist or spray, called Wahh:
About $26 will buy you a Wahh canister, which contains around 25 'puffs' of vaporized alcohol. Hold the lipstick-sized tube up to your mouth, breathe in, and a burst of vodka-flavored mist delivers a dizzying sensation. The feeling fades within seconds, leaving you sober enough to pass a breathalyzer test.
The science behind the vaporizer is pretty simple. Each puff of vapor contains only .075 milliliters of alcohol – the equivalent of about 1/1000th of a shot of liquor. Edwards explains that by vaporizing a single drop of alcohol, Wahh 'increases its surface area by approximately 1,000 times'. In other words, the vapor tricks your brain into thinking that you’re inhaling a thousand droplets of alcohol, rather than one.
