![]() While the jump won’t be as dramatic as last season when some items more than doubled in price from the previous year, many returning fireworks, assortments included, will see increases of 15-25%. Pyrotechnic-passionate patriots of Southern California are about to learn first-hand that prices of fountains, novelties and smoke items and spinners have gone up, and not just in smoke. Supplies should be improved from last season, but consumers are urged to shop early for the best selection. ![]() “There will be increases due to the escalating cost of freight, fuel, raw materials, and other items that will impact pricing compared to 2021,” said Carson Anderson, president of California market leader TNT Fireworks. The same inflated costs of that have consumers paying more for, well, pretty much everything these days, could make honoring our nation’s 246th birthday with fireworks a little less Yankee doodle dandy.

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.
