Feel free to post your shows, discuss your options, and share ideas. The more packed the payload, the louder the BOOM.We're looking for anything to do with fireworks. Inside the shell, the hot gases expand rapidly, building up pressure until they rip through the paper and create a loud boom. Plus it’s good at trapping hot gases but readily gives way for an explosion. It burns quickly and leaves little residue behind. The powdery particles can cause respiratory problems if inhaled-they’ve also been shown to cause lung cancer in rats.Ĭheap, easy, and environmentally friendly, paper (or cardboard) is the perfect packaging for firework shells. It’s also found in safety matches and camouflage paints (Sb 2S 3 helps them reflect infrared!). Ew.Ī dark gray powder, this is added to some star-pellet mixtures to create a glittery effect. It can even replace fat in milk products. The all-purpose water-soluble powder is also used as a binding or thickening agent in paint, processed meats, food glazes, and envelope adhesives. This starchy stuff is often used to bind black powder and metal salts into pellets that explode into colorful stars. Seconds later, a delayed fuse reaches the center of the payload, igniting the main shell to unleash a spectacle of light and sound. The O 2 helps the charcoal and sulfur burn too, producing hot gases that hurl the firework into the sky. As the potassium nitrate burns, it lets off oxygen. In a traditional firework a lit fuse kicks off the reaction, igniting the powder in the bottom of the shell. Invented in ninth-century China, this mix of potassium nitrate, charcoal, and sulfur is what makes fireworks (plus guns and explosives), well, work. Sure, the shows have gotten far more sophisticated-technicians can now time brighter colors, comets, and complex displays to the crescendo of any song. But the chemical cocktail that explodes in showers of color hasn’t changed all that much since those days. Founding father John Adams wanted “illuminations from one end of this continent to the other" to commemorate Independence Day even before the 13 colonies were fully independent. Along with burgers, brats, and BBQ, fireworks are a Fourth of July staple in the US. ![]()
