Fireworks are staples of summer, when neighborhoods sporadically light up with multicolored splendor, and distant pops can be heard on a regular basis.
Most fireworks are made of a small tube called an aerial shell that contains various explosive chemicals, says the American Chemical Company. The shell has gunpowder and something called “stars,” which give fireworks their color when they explode. The shell is housed in a mortar that will launch the firework into the air after a fuse is lit. Ultimately, a bursting charge of the firework explodes and ignites the black powder and stars.
If the stars are randomly placed in the shell, they will produce random patterns. But many fireworks are carefully created so that the stars are placed to allow for specific patterns when the firework explodes. The following are some types of fireworks that surely will be lighting up night skies.
• Brocade: This firework has a large number of trailing stars falling slowly in an umbrella pattern. It’s one of the most common firework effects.
• Cake: Sometimes called a “repeater” or a “multi-shot aerial,” a cake is a firework that has a single fuse used to light several tubes in sequence. They fire at a rapid pace and can sometimes feature more than 1,000 shots. Cakes are often used as part of a show’s finale.
• Chrysanthemum: This is a spherical break of colored stars that leave a visible trail of sparks.
• Firecrackers: These are more about bang than flash. They lay on the ground, and when the fuse is lit, will go off one after another with a loud bang.
• Fountains: These fireworks shoot between four and eight feet into the air and are very colorful. They are sometimes called “driveway items” or “safe and sane” because they don’t propel like other fireworks and may be safer for novices.
• Roman candle: This firework has a paper tube that shoots flaming balls out of one end of the tube.
• Strobe: Similar to other fireworks with a spherical break shape, this has the added effect of blinking components that makes it appear like shimmering water in the sky.
There are many different types of fireworks that add bang and color to evening celebrations.
