shell 56 the firing pin 49 is activated using a capacitor discharge electronic system which has sufficient voltage typically larger than 200 vdc to push firing pin 49 forward with sufficient force and speed to cause shotgun shell 56 to fire a solenoid manufactured by mcmaster carr atlanta ga model no 70155k11 with the piston modified with a bull nose to function as firing pin 49 has been successfully utilized fig6 is a front view of the knife blade 52 and comprises four fin like members 70 which converge to a central area 72 knife blade 52 includes a threaded shaft portion 74 fig4 and 7 which as noted above screws into piston rod 56 fig7 is similar to fig4 and shows knife blade assembly 50 after firing pin 49 has been activated such that shotgun shell 56 has been fired rod 54 is then propelled forward which in turn forces knife blade 52 into side 78 of container 24 rupturing the side and allowing liquid propane 27 contained therein to escape into interior 28 of housing 12 wherein it turns into a gas 80 gas 80 fills the entire interior of housing 12 and mixes with the powder gas escaping from ports 47 formed in cylinder 58 the resultant gas mix igniting and forming a fireball the electro mechanical solenoid pin 49 is activated using a high voltage pulse provided for example by a hand held blasting machine used for igniting electric blasting caps starting with the housing cylinder 12 and end caps 14 and 16 in order to fabricate the fireball generator of the present invention a user unscrews the steel pipe main housing end cap 16 and then inserts tank 24 into the main housing 12 tank 24.
