"Researchers at MIT have discovered a new way for people to communicate with one another, laser beams. These beams are can be targeted to certain people. So if you were in the lasers cross beam, you would be able to hear the audio message.

This all works because of something called “photoacoustic” effect. That is when water vapor in the air absorbs light. Thus creating sound waves allowing us to hear said message. The possibilities for this new technology could be great for military/government purposes. It would allow to send secure messages to anyone in sight without relying on traditional methods, like a mobile device or…well, talking to them. SUPER SECRET! . "
