PROBLEM TO BE SOLVED: To provide a highly amusing toy firework made to cause unexpected motion of jet fireworks accompanying combustion of the toy firework. SOLUTION: A main jet firework 12 is fixed to the tip of a bamboo slat 11, and fireworks with fuse wire 15 are arranged in the circumference of this main jet firework 12. The fireworks with fuse wire 15 are hung by a string 18. The lower ends of fireworks with fuse wire 15 are also ignited by sparks accompanying the combustion of the main jet firework 12. The front lines of combustion of the fireworks with fuse wire 15 scatter about sparks, while moving to the other end side. Then, the fireworks with fuse wire 15 fly about the circumference of the bamboo slat 11, in a state with their being restrained by the string 18 due to the jetting force.
