In the 39 years Kurt Schlueter's family has owned and operated Jeff City Fireworks, some of the top-sellers haven't changed.
People looking to celebrate the Fourth of July are always on the lookout for bottle rockets, smoke balls, fountains, Roman candles and sparklers.
"Sky lanterns are still pretty popular," Schlueter said. "They're quiet and peaceful."
However, new trends continue to evolve, even in the past year or two. One of the latest trends: neon colors.
"There's not just red and blue any more," said Grace Smith, a worker at the stand. Carson Killday, another worker, grabbed a product called "Neon Nightmare" - a $67 shell designed to fill the sky with neon colors - to make her case. Even sparklers can be bought in neon colors now, they said.
Fireworks also aren't just for the Fourth of July. Some people buy them this time of year and hold them for various events, including New Year's celebrations and - the latest trend -baby gender reveal events. Some fireworks are apparently designed for that purpose, with all blue or pink colors.
Jeff City Fireworks is located on U.S. 54 next to Missouri Furniture.
Eastside Fireworks is another family-operated stand. They've been located on Eastland Drive, just outside the city limits, for their 21 years of existence. The operation involves three generations, said Shelly Kiesling, one of the owners.
One of the new popular effects this year, she said, is called Nishiki Kamuro. It's an effect you have seen in professional displays in which the sparks hang in the air for five to seven seconds.
Two displays under their tent feature the Japanese-named effect, including one called "Mother of All Bombs," a nine-shot shell that lasts 50 seconds and costs $80.
Kiesling said sales during this year's Fourth of July holiday might end up being a little slower than some years because the holiday is in the middle of the week.
However, her family is skilled at promoting the business. This year, they've added a "wacky tube man" - also known as an "inflatable arm-flailing tube man" - to catch people's attention.
That's in addition to her daughter, Christa, who displays her talents with hula-hoops for passing vehicles in front of the tent.
Jefferson City's Ben and Brad Thomas visited the stand Sunday with two of their friends, and bought an array of Roman candles, fountains, tanks, parachutes, jumping jacks, smoke balls and, of course, sparklers.
Ben Thomas said they don't buy a lot of expensive shells or displays, just some of the typical fireworks. He said they spread out the celebration throughout the week.
"It's a tradition," Tori McNutt said.
Firework operators said they want their customers to enjoy the experience, and to stay safe.
"Just use common sense," Schlueter said. "Don't hold a lit firework and have a bottle of water available."
