(Newser) – Tens of thousands of people splatted each other with 120 tons of tomatoes during the annual `Tomatina' battle, leaving the eastern Spanish town of Bunol in a sea of red mush. Town hall estimates some 40,000 people, including many tourists, took part in yesterday's hour-long street bombardment, which has its roots in a food fight among kids back in 1945. The town's streets and walls have to be hosed down once the battle ends, and portable showers help participants get clean.
