Do you believe in the power of smiles to transform the world? We do. Coca-Cola sent our people all over the world, from Jamaica to the United Kingdom to Pakistan and more, to simply smile at strangers — to see who would smile back. As we passed others on the street, on the bus or in the park, we gave a smile, held up smiley face posters or did a silly dance with a grin on our faces, all to prompt a little friendliness in the mundane. When someone smiled back, they received a free Coke or some other fun prize: everything from sunglasses to hats to bicycles. Because when you give a smile, lives are changed. And so is the world, one smile at a time.
