On June 21st, the 30,000 visitors that attended the Expo Milano 2015, a six-month-long Universal Exhibition that is currently going on in Milan, Italy, were in for a special treat - a slice of the world's longest pizza! Measuring 1.59545 kilometers, or just under a mile, the delicious pie that extended across 800 tables handily surpassed the previous record holder - a 1.1415-kilometer-long pizza made by Spanish chefs in 2011.
