La Tomatina is a Spanish festival in Buñol, Spain where participants throw tomatoes at each other. It is said to be the biggest food fight in the world. From the festival's origin as a food fight between friends in the 1940s, it has become a famous tourist attraction. Until 2013 there was no limit to the number of participants; in 2013 the festival became a ticketed event for no more than 20,000, so as not to overwhelm Buñol's population of about 9,000 people.
