Imprecise contact between the bridgewire and the primary explosive changes how quickly the explosive is heated up, and minor electrical variations in the wire or leads will change how quickly it heats up as well.
32.
For example, a match will not cause plastic explosive to explode, but it will light a fuse which will detonate a primary explosive that will shock a secondary high explosive and cause it to detonate.
33.
Now yes, it seems ridiculous at first, since the primary explosive inside a blasting cap has a very powerful shockwave, whereas you think of an exploding battery as being a confined gas bursting a container.

"' Fulminating gold "'is a primary explosive first synthesized by alchemists believing it to be the Philosopher's stoneresulting in injuries and accidental deaths from unexpected explosions . " The first high explosive to be made ."
35.
An example is the British World War II " Fuze, Percussion, D . A ., No . 233 " ('direct action') The primary explosive transmits its detonation to an explosive booster within the fuze, then in turn to the main charge of the shell.
36.
It is more difficult to detonate than primary explosives, so dropping or igniting it will typically not cause an explosion ( at atmospheric pressure it is difficult to ignite and burns relatively slowly ), but is more sensitive to shock and friction than other secondary explosives such as TNT or tetryl.
37.
"' D "': Secondary detonating explosive substance or black powder or article containing a secondary detonating explosive substance, in each case without means of initiation and without a propelling charge, or article containing a primary explosive substance and containing two or more effective protective features . ( 1.1D, 1.2D, 1.4D, 1.5D ).

Investigators searching Rudolph's rented trailer in Murphy, North Carolina, in February 1998 found ethylene glycol dinitrate _ the primary explosive ingredient in one type of dynamite _ on a towel, a dark baseball cap and a cushion from a rocking chair, according to an affidavit attached to the original indictment against Rudolph.
39.
"' Cyanuric triazide "'( C 3 N 12 or ( NCN 3 ) 3 ) is described as an environmentally friendly, low toxicity, and organic primary explosive with a detonation velocity of about 7, 300 m�s " 1, and ignition temperature at 205 �C . Primary research on this compound focuses on its use as a high energy density compound.
