"The machine is currently in use in one of the major shopping centres in Barcelona, Spain, where it gives away free Christmas treats in exchange for working of the calories on the bicycle. The aim of the project is to educate people, and especially kids, about obesity, a growing problem in today's society, and consumption habits. The vending machine raises awareness about just how many calories candy contains and how much effort it is to burn them off. Depending on the calories of each product, you need to pedal more or less in order for the vending machine to release it."
