A reusable special effects audible and visual fireball generator device which comprises a cylindrical main housing having end caps mounted at each end. A gas container is positioned within the housing and a knife blade is mounted within the housing adjacent one end cap. A holder containing a predetermined amount of black sporting powder is secured within the housing adjacent the other end cap. When the black sporting powder is ignited, the gas container is forced against the knife blade, rupturing the tank. The released liquid gas mixes with air and the black sporting powder igniting the mixture and providing a fireball effect.
