The pressure cookers were filled with nails, ball bearings, and black powder. Initially, it was believed the devices were triggered by kitchen-type egg timers, however, subsequent evidence indicated a remote device was used to trigger the bombs.
In this manner, what happens if you put nails in a pressure cooker?
In the case of a bomb packed with nails and BBs, that “energetic release” propels deadly shrapnel, including pieces of the pressure cooker itself, in all directions, killing or maiming anyone in the blast path.

What happens when a pressure cooker explodes?
When in use, pressure cookers can have internal temperatures 40 degrees hotter than the boiling point of water. If they explode or forcefully eject liquids or food, their contents can cause severe burns and scalds.

How does a pressure cooker work?
A pressure cooker is a sealed chamber that traps the steam generated as its contents are heated. As steam builds, pressure increases, driving the boiling point of water past 212°F. In general, this higher temperature shortens cooking times and, due to a lack of evaporation, extracts flavor more efficiently from foods.
