Investigators with the Kansas State Fire Marshal's Office and the Hutchinson Fire Department say an explosions that injured six people at the Kansas State Fair was caused by a canned food item that got too hot when stored near a food warmer. The explosion happened at a concession trailer called the Fry Shack. The food can exploded and then the Fry Shack caught on fire. Two people were hospitalized. The 10-day state fair draws about 350,000 people each year. I'm Lisa Dwyer.
