And you thought tweeting from space was an achievement?
Ukrainian TV journalist Julia Gorodetskaya (@gorodetskaya) has sent the first documented underwater tweet from the floor of a 19-feet deep dolphinarium in Odessa, Ukraine. The scuba tweeting session was broadcasted by local media (see subtitled video below) and documented by regional press.
The tweet was sent via a mobile phone sealed in plastic from the Twitter website, using the Opera Mini browser. Radio waves passed to the surface through an elongated antenna.
