HowStuffWorks.com has a fabulous article about how fireworks work, complete with diagrams and animations. I strongly recommend that you try this at home, kids!
| Shell Name | Description |
| Palm | Contains large comets, or charges in the shape of a solid cylinder, that travel outward, explode and then curve downward like the limbs of a palm tree |
| Round shell | Explodes in a spherical shape, usually of colored stars |
| Ring shell | Explodes to produce a symmetrical ring of stars |
| Willow | Contains stars (high charcoal composition makes them long-burning) that fall in the shape of willow branches and may even stay visible until they hit the ground |
| Roundel | Bursts into a circle of maroon shells that explode in sequence |
| Chrysanthemum | Bursts into a spherical pattern of stars that leave a visible trail, with an effect somewhat suggestive of the flower |
| Pistil | Like a chrysanthemum shell, but has a core that is a different color from the outer stars |
| Maroon shell | Makes a loud bang |
| Serpentine | Bursts to send small tubes of incendiaries skittering outward in random paths, which may culminate in exploding stars |
