What is a pressure cooker bomb?
A pressure cooker bomb is an improvised explosive device that utilizes a pressure cooker as its main container. This type of bomb typically includes explosive materials, shrapnel, and a fuse. The pressure cooker is designed to withstand high-pressure environments, which allows it to contain and rapidly build up harmful pressure until it ultimately explodes. The resulting detonation creates a powerful blast wave and fragments, which can cause significant damage and injuries.
The mechanism behind a pressure cooker bomb functions by leveraging the principles of pressure cooking. In a standard pressure cooker, food is cooked while steam builds up, increasing the internal pressure. When modified for explosive purposes, the bombmaker aims to create a similar build-up of pressure until the cooker cannot contain it any longer, resulting in a catastrophic explosion. The shrapnel can include any sharp materials placed inside the cooker, further increasing the lethality of the device.
How do pressure cooker bombs differ from traditional explosives?
Pressure cooker bombs differ primarily in their construction and the materials used. Traditional explosives often consist of pre-manufactured compounds, such as TNT or C4, which are designed to detonate upon being ignited or subjected to a shockwave. In contrast, pressure cooker bombs are typically assembled using household items and readily available ingredients. This makes them more accessible for individuals looking to create improvised devices.
Moreover, unlike many traditional explosives that function on a quick detonation basis, pressure cooker bombs rely on the buildup of pressure before explosion. They can be triggered using various methods, such as timers, remote controls, or direct contact with a flame.
