For today only, (September 3) Coca-Cola is giving away free product to celebrate their sponsorship of London 2012. People in Britain can go to freecoke.co.uk to claim their product code.
To promote the giveaway, they constructed a 100 foot tall replica of a Coca-Cola vending machine, complete with giant ‘push’ button.
Coca-Cola is well-known for their interactive ‘Happiness Machines’ including; one in Singapore that responded to hugs, and one in Turkey that gave away free coca-cola to couples only. (note these vedning machines were activated by remote control, and did not include image recognition or senors)
