Pipe bomb


Pipe bomb

A pipe bomb is an improvised explosive device, a tightly sealed section of pipe filled with an explosive material. The containment provided by the pipe means that simple low explosives can be used to produce a relatively large explosion, and the fragmentation of the pipe itself creates potentially lethal shrapnel.

Premature detonation is a hazard of attempting to construct any homemade bomb, and the materials and methods used with pipe bombs make unintentional detonation incidents common, usually resulting in serious injury or death to the assembler.

In many countries the manufacture or possession of a pipe bomb is a serious crime, regardless of its intended use.

Design

The bomb is usually a short section of steel water pipe containing the explosive mixture and closed at both ends with steel or brass caps. A fuse is inserted into the pipe with a lead running out through a hole in the side or capped end of the pipe. The fuse can be electric with wires leading to a timer and battery or can be a common fuse such as used in most consumer fireworks. All of the components are easily obtainable.

Generally high explosives such as TNT are "not" used, because these and the detonators they require are difficult to obtain. Such explosives also don't require the containment of a pipe bomb. Instead, any sort of explosive mixture the builder can find or make is used.

Some of the explosive mixtures used, such as black powder, match heads or chlorate mixtures are very prone to ignition by the friction and static electricity generated when packing the material inside the tube or attaching the end caps - accounting for many injuries or deaths amongst builders. If sharp objects, such as nails or broken glass, are added inside the bomb in an attempt to increase the amount of injury, these also add to the risk of premature ignition.

The addition of loosely fixed shrapnel material outside of the bomb can increase the danger of the explosion cheaply and easily. The Unabomber used this method by taping carpentry nails to the outside of his devices. Other variations include using scrap metal or ball bearings.

Devices made from plastic pipe, such as PVC, or thick walled cardboard tube would not be normally considered as "pipe bombs".

Uses

Pipe bombs are often used by criminals, as well as paramilitaries and militias. They also have a long tradition of recreational use for amusement or mischief with no intention to cause injury to anyone - but the dangers of premature ignition, and the inherent danger of shrapnel mean that when used in such a manner they are much more dangerous than alternatives such as dry ice bomb or spud gun.

*On 4 May 1886, a gas-pipe bomb was thrown during a rally at Haymarket Square in Chicago, Illinois.cite book |title= American State Trials: A Collection of the Important and Interesting Criminal Trials which Have Taken Place in the United States from the Beginning of Our Government to the Present Day|last= Lawson|first= John Davison |coauthors= Robert Lorenzo Howard|year= 1919|publisher=Thomas Law Books|pages= 64|url= http://books.google.com/books?id=kfIUAAAAYAAJ&pg=PA64&dq=a+fuse+with+a+cap+is+put+into+that+hole] The gas-pipe bomb reached a police line and exploded, killing policeman Mathias J. Degan. The thrown bomb was made from gas-pipe filled with dynamite and capped at both ends with wooden blocks. Old nails were secured tightly by wire around the gas-pipe, which had a hole that received a fuse with a cap. The event became known as the infamous Haymarket riots.
