A vending machine that gives customers iced tea in return for tweets has been installed in Cape Town, South Africa. Launched by South African soft drinks company BOS Ice Tea, the vending machine is called Bev. To receive a free sample of BOS Ice Tea, users need to tweet a certain hashtag, the # symbol commonly used on micro-blogging service Twitter to identify topics. The drink is made from Rooibos, a local plant used to make traditional tea. To make the machine respond to tweets, its developers configured a specific hashtag as a filter. When the hashtag appears on Twitter, the vending machine checks it and – if correct – gives out a drink.
