Pipe bomb

A pipe bomb usually consists of a container such as a piece of pipe filled with an explosive material. The pressure of the burning explosive material ruptures the pipe resulting in a sudden, explosive release. The rupturing pipe creates fragmentation, which can lead to injury.

Premature detonation is an occupational hazard of attempting to construct homemade explosive devices. Documented instances of unintentional detonation while the bomb is being constructed are common, often resulting in serious injury or death to the assembler.

In many countries the manufacture of a pipe bomb is a serious criminal offense, even if experimentation is the only intent.
