A floatable firework device includes a hollow base for fitting an explosive therein, a waterproof fuse, and a tubular buoyancy member sleeved fixedly around an upper portion of the base. The base has a center of gravity at a lower end portion thereof. As such, the firework device can float on a water surface, with a flame-spraying upper end slit in the base being disposed above the water surface.
