Did you know that a typical 20 minute forth of July fireworks display can take a year to plan, and it costs more than a new car? Not only that, each show is programmed with computers and remote controls used to ignite the fuses. Want to learn more? Let’s test your knowledge of fireworks displays.

1. We all know what a fireworks shell looks like in the night sky. But what does it look like BEFORE it explodes?  At Popular Mechanics you can see that fireworks shells come in all shapes and sizes. Smaller shells are the size of tennis balls, but they can get as big as a basketball. To launch one, you put it into a pipe (called a Mortar tube) light the fuse and run away.

2. Where are fireworks made? CNN  http://cnn.it/TIpkvg visited a fireworks factory in China, located in Iuyang in the Hunan Province, where nearly all the world’s fireworks are made. Have a look, and you’ll see how it earned it’s nickname of “Boomtown.”

3. Who holds the world record for the largest, most expensive fireworks display? According to the Guinness World Records, at  the United Arab Emirates put on a fireworks display in December of 2013 that used half a million fireworks, costing between $50 to $100 each. Do the math… that’s a lot of money. Read more about this amazing show, here http://bit.ly/1k53LAT or watch it in the video playlist, below.

4. How much does a fireworks display cost? To find out, we visited Michigan-based Ace Pyro http://www.acepyro.com/Faqs where we learned that the average cost of a 20 minute fireworks show is between $5,000 and $30,000. A big show, like the Macy’s show in New York City can cost between $5 to $10 million. Each time you see a firey burst, think “there goes $100.”

5. How do you design a fireworks show? It takes many people, including choreographers, laborers, technicians, and city officials, plus about 4 hours per minute for the design. Many designers use a program like Finale Fireworks ($1000, from www.finalefireworks.com) on a Windows computer to mix and match as many as 6,000 different effects. The best thing about the software is that you can preview the show with the click of a mouse instead of by lighting the fuse.

6. How are colors made when a shell explodes? At the University of Wisconsin, http://bit.ly/RVImxu you can learn all about the different chemical compounds scientist use to create different color fireworks. There is even a chart with the compounds needed to create nine different color combinations. The people who use the chart are called pyrotechnic engineers, and they make about $90,000/year.
