Investigators believe the bombs at the Boston Marathon were shrapnel-studded pressure cookers, hidden in backpacks and set off by timers, law enforcement officials told NBC News on Tuesday.
A pressure cooker, in its everyday use, speeds cooking by creating a tight seal and building pressure inside the pot. Converting it to a bomb sheaths the explosives in a metal casing, which blows apart when the bomb is detonated and adds to the shrapnel already packed inside.
