The Art and Science of the Fish Firework Effect

There’s a certain flair to fireworks that imitate nature, and few effects capture this more uniquely than the fish firework effect. Imagine bright, glowing shapes darting, wiggling and swimming their way through the air. It's like watching a handful of luminous fish flit across a dark ocean—and all it takes is a bit of pyrotechnic wizardry.

The fish effect has been amusing and amazing firework audiences for years, but what actually makes it tick? Let’s take a deep dive into this eccentric yet fascinating display.

What Exactly Is the Fish Firework Effect?

The fish firework effect is a display that simulates small, glowing shapes—often golden or brightly coloured—that appear to “swim” through the sky. When ignited, these small “fish” travel independently in different directions, often moving in short, zigzag or swooping patterns. It’s a bit of controlled chaos, with each particle zipping about as though it has a mind of its own.

Despite the name, fish effects can evoke a range of imagery for spectators. Some might see a school of fish, others might think of fireflies or playful stars. But what’s certain is that it’s one of the most distinctive effects in the world of fireworks, bringing an unusual dynamic to any display.

What Sets the Fish Effect Apart from Other Firework Effects?

The fish effect is unlike the more traditional explosions of colour and light. Instead of producing a symmetrical burst or a slow descent, fish effects are all about movement. While other firework effects focus on creating static or patterned designs in the sky, the fish effect is full of unpredictable motion.

This movement is achieved with carefully engineered particles that travel independently, mimicking the way fish dart about in water. The result is lively and spontaneous, with each “fish” following its own path. This makes fish effects an ideal choice for adding a sense of playfulness to a display, offering a break from more rigid or formulaic effects like chrysanthemums or willows.

Another defining trait is the sense of scale. Fish effects are typically smaller and more contained than other firework effects, so they work well as a subtle yet eye-catching element within a larger show. And because of the way they move, they provide a lighthearted, almost comical break in a sequence of more traditional fireworks, often drawing smiles from audiences.

How Is the Fish Effect Achieved?

Creating the fish effect is a matter of clever chemistry and pyrotechnic design. The magic lies in the use of propellant particles, also known as “micro-stars.” When the shell bursts, these micro-stars ignite, propelling themselves forward in erratic directions rather than simply burning in place.

These tiny stars contain an extra kick of propulsion fuel, giving them just enough thrust to shoot off in their own directions rather than falling directly to the ground. Some of the fish effects may even contain metallic elements like titanium or aluminium to produce a shimmering or sparkling effect as they dart around.

Manufacturers carefully measure the propellant to ensure each fish particle has the right amount of thrust and speed. It’s a delicate balance: too little, and they might not achieve the desired motion; too much, and they risk burning too brightly and dissipating before the audience can appreciate their “swimming” paths. By combining the right chemicals, shapes, and sizes, pyrotechnicians can control the motion, ensuring those fishy particles don’t just shine—they dart, they dash, and they swim.

The History of the Fish Effect

Compared to the grander, more traditional fireworks, the fish effect is a relatively modern addition to the pyrotechnic repertoire. Fireworks have been around for centuries, but the fish effect emerged only within the last several decades as pyrotechnic technology evolved to allow for more precision.

The fish effect grew in popularity alongside the development of more diverse fireworks displays, especially as audiences started to expect more creativity and variety in their shows. It’s a quirky effect that broke the mould and added an unexpected visual surprise, fitting right in with the growing interest in innovative, experimental pyrotechnics.

Since its introduction, the fish effect has become a staple of many large displays, particularly in sequences where organisers want to inject a bit of charm and unpredictability.

The Evolution, Variations, and Interpretations of the Fish Effect

While the classic fish effect remains a popular choice, there are a few twists on the original that add even more personality to the effect.

• Coloured Fish: Traditionally, fish effects were limited to golden or white particles, but modern displays have introduced vibrant colours to the mix. Now, you can see everything from red and green fish to dazzling blue and yellow, allowing designers to coordinate the effect with other elements of the show.

• Double Fish: In some variations, each “fish” particle is actually made up of two connected micro-stars. When ignited, these particles split off in two directions, creating a sort of mirrored effect that doubles the amount of motion and adds to the visual spectacle.

• Fish with Crackling Tails: Some fish effects add a crackling tail to each particle, enhancing the swimming effect with a little extra sound and visual texture. The crackling mimics the sound of water bubbling, giving the illusion that these fiery fish are swimming through a bubbly underwater world.

• Swarm Fish Effect: This variant is particularly popular in large displays, as it involves a denser number of particles to simulate a “school” of fish moving together. When launched, they create the impression of a large group darting across the sky, creating a more dramatic and sweeping motion.

These variations offer pyrotechnicians endless possibilities to tweak and personalise the fish effect, tailoring it to specific themes or audiences. For example, themed events like ocean festivals or marine-themed fireworks displays can use fish effects to add a creative, on-topic twist to their shows.
