4th Quarter
Enjoy my first experience seeing a firework show for 4th quarter!!
Is this normal in college football!? I visited Troy University and got to experience this! I thought it was so cool!
Side note: I attend a NAIA (pwi) so this is not a thing for us, football is just not taken as serious.
At my high school it was so I often miss FNL!? Don’t get me wrong I love a good hoop session. It’s just still something about the lights and over excitement at a football game that just makes my night!
Wow, those college football fireworks truly left an impression on me! After watching them light up the sky at Troy University, I found myself completely mesmerized and got super curious: how do they actually work? Especially thinking about how perfectly timed and placed each burst was. It turns out, there's a whole lot of science and even some math – yes, trigonometry! – that goes into making those dazzling displays happen. I started doing a little digging, and it’s pretty fascinating. When you see a firework rocket launch into the air, it’s not just random. Pyrotechnicians (the amazing people who design these shows!) use principles of physics and math to predict exactly where and when each firework will explode. Think about it: they need to control the height, the spread, and the timing of the burst to create those incredible patterns. This is where trigonometry comes into play. Remember learning about angles, distances, and heights in geometry or physics class? Well, those concepts are essential for fireworks. When a firework shell is launched from a mortar, it travels in a parabolic arc. To calculate this path, pyrotechnicians consider several factors: the initial launch velocity (how fast it leaves the mortar), the launch angle (how steep it’s fired), and the force of gravity pulling it back down. Using trigonometric functions like sine and cosine, they can determine things like the maximum height the firework will reach and how far away it will land if it didn't burst. For instance, if they want a firework to burst at a specific altitude, they'll adjust the launch angle and the amount of lift powder. A higher angle might send it higher, but not as far horizontally, while a lower angle will give it more horizontal range but less height. It's all about balancing these variables. But it’s not just about getting it up there! The timing of the burst is crucial. Inside each firework shell are 'stars' (the pellets that create the colors and sparks) and a burst charge. A fuse is lit when the firework is launched, and its length is precisely calculated so that the burst charge ignites at the peak of the firework's trajectory – or exactly where they want the explosion to occur. If the fuse is too short, it might burst too low; too long, and it might ascend past its optimal point or even fall before bursting. Trigonometry helps in calculating the flight time to ensure the fuse length is perfect for that ideal burst point. Even the spread of the stars within the burst is considered. The way the burst charge disperses the stars, and the angle at which they fly outwards, contributes to the final shape and size of the explosion. Whether it’s a perfect sphere, a cascading willow, or a glittering chrysanthemum, the physics of expansion and the initial angles of the ejected stars are all part of the design. It truly adds another layer of appreciation to these spectacular shows. Next time I’m at a game, watching those fireworks explode in the "4th quarter," I’ll not only be marveling at the beauty but also thinking about the incredible engineering and mathematical precision that makes it all possible. Who knew my college football experience would lead me down this rabbit hole of pyro-physics? It just goes to show, there's always something new to learn, even from the most exciting gameday traditions!
