Twitter has been the catalyst for many things, but this is the first time we've heard of it being used to locate missing golf balls.
Evian (which is great at social-media stunts) is launching a competition centered around its sponsorship of ladies' golf tournament The Evian Championship, which takes place in France this week. From today through Sunday, fans can guess the location of missing balls by tweeting the coordinates on a Google map of the geographical area corresponding to the golf course. The game is laid out in grid form in the style of the board game Battleship, and players can guess the location of the missing balls on Twitter using the coordinates of where they think the ball could be. All they need to do is tweet hashtag #TweetTheBall along with the grid reference. Every ball finder will get a reward and be entered into a drawing to win a two-night hotel stay. The execution is by digital agency Nedd.
