Two researchers from York University in Canada used vodka evaporated into the air to establish communication between two points and successfully sent the lyrics of "O Canada." The researchers said that in the event that cell-phone cellular has no signal, this system can be used to send text messages. The researchers used a specific vodka concentration to represent 1 and 0, reading out the information by measuring the fluctuation of vodka concentration in the air over time. In the lab, they successfully delivered the information to the receiving unit 12 feet away. Although the system was too close to being transmitted, the researchers stated that it could work in a closed space without wireless signals.
