In this fun video, chocolate enthusiast James Ward describes how he visited more than 140 locations in London checking the price and sale condition of Cadbury’s Twirl chocolate bars. One of his slides includes the economist Adam Smith, and Ward sees his Twirl project as providing consumers with the information they need for the market to function smoothly. With his Google Map, you can save yourself as much as 10p by locating the cheapest Twirl on your street.
Ward even generated some statistics from his data, although he admits his correlation of shop name and Twirl availability is “worthless”. No one can accuse him of taking himself too seriously.
