PURPOSE: To provide a novel structure of a toy firework able to fly, what is called a rocket firework, wherein when it flies, a sound of flute is generated, following which a sound of explosion is generated.

CONSTITUTION: Powders 2, 3 are properly loaded in a cylindrical casing 1, one of the ends of which is closed. When the powder 3 burns, the sound of a flute is generated while a firework is flying, following which a sound of explosion is generated, wherein a partition lip 15 extending toward the center of the casing 1 is provided along the inner surface of the casing 1. The explosion sound powder 2, wherein it is required that there is a sufficient gap around the powder and the powder itself is in a relatively rough particle-like state, is loaded in an explosion sound powder chamber 12 and thereafter the powder loaded is maintained in such a state that it is separated by the lip 15 from the pressure of the powder 3 which is loaded in the following step, and hence a sound of explosion can be obtained without fail.
