An explosive device for making noise combined with a keychain comprises a barrel having a bore formed therein accommodating a blank. The device also has a pin disposed in the bore of the barrel and a spring surrounding the periphery of the pin. A ring member connects with the pin. The device makes noise by manually moving the ring member between a first and a second position. The ring member rests against a stop in the barrel remote from the blank in the first position. The ring member releases from the stop, permitting the pin to strike the blank in the barrel under force of the spring, in the second position.
