An aerial fireworks product has an exploding part that produces desired sights and sounds upon reaching an appropriate height above the ground, and a non-exploding part that returns to earth following the explosion. An air brake as part of the device is integrated into the structure in such a manner that it provides little or no in-flight drag during launching of the device. However, upon explosion, the brake bursts out into petals or flaps that remain secured to the non-exploding part so as to create additional air drag to retard the descent of the non-exploding part. In its preferred form, the brake is in the nature of a paper collar secured to the stabilizing base of the product yet positioned in close proximity to the exploding part so as to burst into the air drag-creating configuration upon denotation of the exploding part.

1. In a self-propelled aerial pyrotechnic device, the improvement comprising:an exploding part adapted to detonate when the device has propelled itself to a height above the ground; a non-exploding part adapted to return to earth by gravity following detonation of the exploding part; and an air brake secured to the non-exploding part, said air brake being configured and arranged to be substantially ineffective during lift-off of the device but constructed of such a material and so disposed with respect to the exploding part as to rupture under the force of the explosion to form petal-like residue attached to the non-exploding part that increases its drag and retards its descent as it returns to earth.
