Giving a whole new meaning to the phrase “drunk text,” York University researchers in Canada have used vodka and a desk fan to send a new kind of text message. In the experiment, they encoded the alphabet in evaporated alcohol, assigning different concentration levels to represent bits 1 and 0. The chemical signal was then sprayed 12 feet across the room where it was then decoded by a receiver measuring the increase and decrease of alcohol concentration. The varying concentration levels spelled out the appropriate text, “O Canada.”

Say it, don’t spray it.
