Abstract: A noisemaking toy, more particularly, a simulated firecracker is presented which includes an elongate hollow cylindrical body and an elongated cord extending from one end; a piston assembly located within the body attached to the cord; a compression spring is provided for driving the piston; and a cap detonating assembly is located at the remote end of the body, the assembly containing a trigger mechanism which extends within the cylinder in the path of travel of the piston; and a sound generating means for emitting a whistle is coupled to the piston; whereby withdrawal of the cord to retract the piston and compress the spring, followed by release of the cord, allows the piston to travel forward along the axis of the body at a controlled rate, providing a whistling sound for a predetermined interval of time followed by the actuation of the cap detonating means.
