A pressure cooker bomb, like the ones used in the 2013 Boston Marathon bombing, is an IED created by inserting explosive material into a pressure cooker and attaching a blasting cap. Pictured here, a piece of one of the Boston Marathon 2013 bombs, believed to be a pressure cooker, which was discovered the day after the April 15, 2013 explosion. (Image courtesy of the FBI)
