This invention concerns a rocket firecracker giving out smoke before flying up. It comprises a shooting-up tube, a smoke tube, a fuse, a flying wing, and a launch pad. The shooting-up tube not only contains shooting-up chemicals but also the smoke tube filled with smoking chemicals set inside its lower part and when the smoking chemicals have been burned up giving out a lot of smoke and the firecracker has flown up in the air for a short while with the shooting-up chemicals being burned, the smoke tube with its chemicals burned up can be blown off the shooting-up tube and fall down, but the firecracker still continues to fly up till all the shooting-up chemicals are used up.

A firecracker for simulating the launching and flight of a multi-stage rocket, the firecracker comprising an outer shoot-up tube having and upper closed nose end and an open lower end, ignitable propulsion chemical means in the nose end of the shoot-up tube, a smoke tube for receipt in the shoot-up tube below said chemical means, the smoke tube containing smoke-producing chemical means, a fuse for igniting the smoke-producing chemical means extending from one end of the smoke tube, a finned wing structure for the lower end of the shoot-up tube, and a launch pad member for supporting the shoot-up tube and wing structure in upright launch position with the smoke tube inserted in the shoot-up tube and the fuse extending there-below, the smoke-producing chemical means when ignited by the fuse being effective for ejecting smoke from the lower end of the shoot-up tube and subsequently igniting the propulsion chemical means, they propulsion chemical means when ignited being effective for developing pressure within tubes to launch the tubes from the launch pad means into upward flight and subsequently separate the tubes whereby the smoke tube may fall to earth with continued upward flight of the shoot-up tube.
