Atime bomb (or atimebomb, time-bomb) is abomb whosedetonation is triggered by atimer. The use or attempted use of time bombs has been for various purposes includinginsurance fraud,terrorism,assassination,sabotage andwarfare. They are a frequent plot device inthriller andaction films as they offer a way of imparting a dramatic sense of urgency.
Theexplosive charge is the main component of any bomb, and makes up most of the size and weight of it. It is the damaging element of the bomb (along with any fragments orshrapnel the explosion might produce with its container or neighboring objects). The explosive charge is detonated by adetonator.
A time bomb's timing mechanism may be professionally manufactured either separately or as part of the device, or it may beimprovised from an ordinary household timer such as a wind-upalarm clock,wrist watch, digital kitchen timer, ornotebook computer. The timer can be programmed to count up or count down (usually the latter; as the bomb detonates when the time runs out).
