Festival ball comets are inexpensive, easy to assemble and produce a nice effect. Before discussing their construction, let me acknowledge that, as far as I know, the basic idea for this firework originated with Bob Winokur.
The device consists of a festival ball shell with comet composition coating the fuse end of the shell. Festival balls are small Class “C” aerial shells, about 1-3/4" in diameter and are usually painted red in color. Unlifted, they cost about $20.00 per hundred. Kits of 12 lifted shells with a mortar are available for five or six dollars. The small shells have stars of any of several colors and are a fairly effective firework for the price.
