Capetonians, when last did you visit Wembley Square? If it was this weekend, you may have noticed that BOS Ice Tea has launched the world’s first Twitter-activated sampling machine there.

BEV, the whirling, bleeping, buzzing BOS Ice Tea-vending robot, made her debut appearance at the 2012 Design Indaba, where she spent her time refreshing and amusing delegates and the public.

She was originally triggered using tokens, and rigged with speakers and cameras to show her inner workings, but BEV has recently been tweaked to respond to tweets!

She now delivers a refreshing BOS Ice Tea whenever a tweet is posted with her unique hashtag.

Find BEV at Wembley Square, next to Sinn’s restaurant, where she’ll be “in residence” until Friday 22 June 2012.

When you find her, she’ll reveal her secret hashtag, and reward your curiosity with a revitalising free can of BOS Ice Tea when you tweet about her.

“At the Design Indaba, BEV became known for her giving nature. The next step in her extraordinary evolution was to link up the real world of sampling a refreshing BOS Ice Tea with the virtual world of sharing experiences and social interaction,” says Grant Rushmere, co-founder of BOS Ice Tea.

The vending machine is rigged with a series of microphones, cameras, trigger switches and sound-activated LED’s to amplify the machine’s personality, and she’s sure to charm you.
