There's now a bar in London, Alcoholic Architecture, that serves breathable alcohol.
Located in a basement in Borough Market, Alcoholic Architecture allows you to get buzzed by breathing in vaporized alcohol.
With this method, alcohol bypasses your liver and is absorbed into your bloodstream through your lungs and eyes.
The entire process begins by entering "the cloud," which is a room that contains a 1:3 ratio of spirits and mixer. Humidifiers are used to keep the air and alcohol saturated while guests enjoy a good time.
