Fireworks are one of the biggest parts of the Fourth of July. Most people plan their whole day around finding the best fireworks show in their area. While most people enjoy watching the dazzling and colorful explosions, they do not realize all of the science that goes into creating a fireworks show.
The first firework was created by a Chinese monk who filled a piece of bamboo with gunpowder and threw it in a fire to create a bang that would scare the ghosts away. While most of today’s fireworks are more complex than that and are not typically used to scare ghosts, they are made in the same basic way, just using a little more technology.
It was not until the Italian Renaissance that steel and charcoal were added to create orange and yellow colors in fireworks. Throughout the years, pyro-technicians have experimented with different metals to create all of the colors that are common in current firework shows.
In order to get fireworks to fly as high as they do, technicians load the fireworks into a mortar, which is basically just a small cannon. They then light a fast-burning fuse that lights gunpowder that is stored in a separate bottom compartment of the firework, which sends it flying through the sky.
The fireworks themselves are made up of different shells. The first is usually made of plastic or paper, which holds everything together. These shells are stuffed full of gunpowder, which has explosive spheres known as “stars” embedded. These stars are what become the points of light when the firework explodes. The different metals that the stars are coated with determine what color the firework is.
Inside the firework is a time delay fuse, which is lit at the same time as the fast-burning fuse, which sends the firework flying, but it takes much longer to reach the gunpowder that is inside the firework. The length of the fuse determines how high the firework will be when it explodes.
One of the down sides to these large explosions is that they are not easily caught on film, especially by smartphones. Luckily, there is new technology which helps you capture firework bursts. The app “LightBomber” gives your phone camera a long exposure, which will allow it to capture all the magic of the different fireworks. It also offers a “light trail” mode that will capture color bursts that look as real as seeing the fireworks in real life.
