The briefcase bomb used in the July 20 plot used a captured British pencil detonator inserted into a block of British plastic explosives weighing approximately two pounds. The bomb was set to 30 minutes and detonated as planned, but Hitler survived with minor injuries. Stauffenberg could not prepare the second block, though. He got rid of it ...
It has since been set backward 8 times and forward 18 times. The farthest time from midnight was 17 minutes in 1991, and the nearest is 89 seconds, set in January 2025. The Clock was moved to 150 seconds (2 minutes, 30 seconds) in 2017, then forward to 2 minutes to midnight in 2018, and left unchanged in 2019. [6]
[5] [6] The piece continues until it gets to Pakistan's first nuclear test in 1998. [7] The total number of weapons detonated is 2053. [8] The piece used sound and light to startle the viewer. [9] Months (measured in seconds) are represented by a sound. [10] When a nuclear explosion occurs, a musical sound plays. [11]
A time bomb's timing mechanism may be professionally manufactured either separately or as part of the device, or it may be improvised from an ordinary household timer such as a wind-up alarm clock, wrist watch, digital kitchen timer, or notebook computer. The timer can be programmed to count up or count down (usually the latter; as the bomb ...
[38] [40] [41] [42] Furthermore, following the bright flash of light of the nuclear fireball, the explosion's blast wave would take from first light, 7 to 10 seconds to reach a person standing 3 km from the surface of the nuclear fireball, with the exact time of arrival being dependent on the speed of sound in air in their area.
A disadvantage of the Lewes bomb was that the detonators could be unreliable; several raids failed when their pencil-detonators were rendered unusable by heavy rain. [4] The timing of the detonators could also be affected by the desert heat; after a raid in December 1941 one party reported the 30-minute time pencils had detonated in just 18 ...
The first, a suicide bomb, is detonated in a small nightclub across the road from another nightclub, the Sari Club. A second bomb, a truck filled with explosives parked outside the Sari Club explodes 15 seconds after the first. Less than a minute later, a third bomb detonates outside the United States Consulate. The total death toll is 202.
The MOAB is the most powerful conventional bomb ever used in combat as measured by the weight of its explosive material. [29] [30] The explosive yield is comparable to that of the smallest tactical nuclear weapons, such as the Cold War-era American M-388 projectile fired by the portable Davy Crockett recoilless gun.
