How do electric detonators work?
electric detonator – any device containing an initiating or primary explosive that is used for initiating detonation in another explosives material and uses direct electrical energy from the device’s leads (wires, springs, contacts, etc.) to fire an igniter to initiate the device.
How are detonators made?
A detonator, frequently a blasting cap, is a device used to trigger an explosive device. This compound is formed from lead azide, lead styphnate and aluminium and is pressed into place above the base charge, usually TNT or tetryl in military detonators and PETN in commercial detonators.

How are phones used as detonators?
Cellphones are basically just small, sophisticated radios. They convert a radio signal into an electrical current and then process that current into sound. Incorporated into a bomb, a cellphone’s electrical current is enough to jolt a small detonator charge, which in turn can set off the main explosive.
Are blasting caps illegal?
No person shall store or keep blasting caps, detonating or fulminating caps, or detonators in a magazine in which any other type of explosive is stored or kept.
How is gelatin sticks made?
Gelignite (/ˈdʒɛlɪɡnaɪt/), also known as blasting gelatin or simply “jelly”, is an explosive material consisting of collodion-cotton (a type of nitrocellulose or guncotton) dissolved in either nitroglycerine or nitroglycol and mixed with wood pulp and saltpetre (sodium nitrate or potassium nitrate).

Who dropped the Fat Man?
Major Charles Sweeney
National Museum of the U.S. Navy The atomic bomb used at Nagasaki on August 9, 1945, was “Fat Man”. The bomb was dropped by a USAAF B-29 airplane named “Bockscar”, piloted by U.S. Army Air Force Major Charles Sweeney. The bomb weighed 10,000 pounds and had a diameter of 60 inches.
How much Tannerite equals a stick of dynamite?
No more than four ounces should be used at one. “Usually they come in two or four ounce containers you’re pretty safe 100 feet away with those but two pounds you’d have to be about 300 yards probably,” says Carlson. He says two pounds of Tannerite is equivalent to two sticks of dynamite.
What does TNT stand for?
Trinitrotoluene
TNT/Full name
trinitrotoluene (TNT), a pale yellow, solid organic nitrogen compound used chiefly as an explosive, prepared by stepwise nitration of toluene.
Who invented Gelignite?
Alfred Nobel
Gelignite/Inventors
One the commonest explosives, gelignite was invented by Alfred Nobel in 1875, and is widely used in mining and demolition.
What is an electelectronic detonator?
Electronic detonators have two important features. The first feature is feedback. With non-electric detonators, once the hole is loaded and the caps hooked together, there is no way of knowing whether the tubing has been accidentally severed or some other underground issue that would cause the non-electric det not to fire.
Can cell phones be used to set off bombs?
Bombers use the cell phone as a typical remote control: to send a signal via radio airwaves. The signal energizes a relay connected to a blasting cap, which in turn detonates explosive material. Although remote controlled toys and keyless entry devices set off bombs too, cell phones remain the most popular.
Can cell phones be used as weapons of terrorism?
Notably, cell phones detonated the bombs that destroyed public transportation in Madrid and London in 2004 and 2005 respectively; terrorists also planned to use them to bomb commercial U.S. flights in August 2006.
How many detonators can be fired from one blast box?
By using the SMI 110 system typically 454 detonators could be fired (at a 19ms inter hole delay) per blast box without sacrificing accuracy and ensuring single hole firing. In later years the SMI 200 series system unlimited numbers of detonators could be fired by simply adding additional blast boxes.
