WTF by Vivid Pyrotechnics

WTF by Vivid Pyrotechnics – 512-Shot 1.3G Compound Firework

When you see it, you will understand why it is called WTF. Vivid Pyrotechnics' most notorious and best-selling compound firework is a jaw-dropping 512-shot professional compound that fires eight pre-fused 64-shot hard-hitting cakes in a relentless machine-gun barrage of noise and colour for 175 seconds — two minutes and fifty-five seconds of continuous, maximum-noise, sky-dominating performance from a single ignition point.

Loaded with a staggering 3,992g of powder weight and firing in rapid straight volleys of six simultaneous shots that multiply the impact of every burst sixfold, WTF reaches a towering 30 metres and fills the entire vertical sky from the very first ignition to the very last shot. Brocades, golden willows, strobing dahlias, chrysanthemum crackles, coloured peonies, glittering stars, and palm bursts cascade in uninterrupted succession — each of the eight pre-fused cakes delivering its own distinct intense display before the next fires automatically and the sky fills all over again.

With a 5 out of 5 noise rating, 1.3G hazard classification, and a 15-metre safety distance that makes it one of the most accessible professional-grade compounds available, WTF by Vivid Pyrotechnics is not just a firework. It is the firework. And once you have seen it, there is only one thing left to say.

Technical Specifications

Performance & Effects

Structure — Eight Pre-Fused Cakes, One Ignition Point

WTF is unlike any standard single compound firework. Rather than one product with multiple internal sections, WTF is eight individual 64-shot hard-hitting cakes — each designed and loaded with its own distinct effect combinations — pre-fused together at the factory and mounted on a single board for easy deployment. One fuse. Eight cakes. 512 shots. Each cake transitions seamlessly into the next without pause, creating a continuous 175-second performance where every 64-shot section brings an entirely new set of effects to the sky.

Firing Mechanism — Volleys of Six

WTF fires its 20mm tubes in simultaneous volleys of six shots at a time — meaning every single burst in the sky is actually six individual effects exploding together in a tight cluster at 30 metres. This multiplies the visual impact of WTF's 20mm tubes by six on every single volley, creating burst densities and sky coverage that dramatically exceed what the tube size alone would suggest. At 512 shots spread across 175 seconds in volleys of six, the pace is relentless and the sky is never empty.

Effects — Brocades, Golden Willows, Strobing Dahlias & More

Across the eight cakes, WTF cycles through one of the most comprehensive effect lists available in any single consumer compound firework in the UK market:

Brocades — dense, fine cascading silver-gold trails that fill the sky with shimmering light and exceptional hang time, overlapping continuously in WTF's rapid-fire volleys to create an almost unbroken golden canopy.

Golden Willows — enormous drooping trails of warm golden stars that hang and drift before fading, the iconic willow effect producing the most visually graceful moments in WTF's relentless sequence.

Strobing Dahlias — full-sphere dahlia bursts of vivid coloured stars that flash rhythmically with strobe pulses, combining the bold visual impact of the dahlia shape with the dynamic, pulsing energy of strobe effects in multiple colours throughout the eight cakes.

Chrysanthemum Crackles — multi-trailing crackle bursts where stars fan outward in graceful arcs before erupting into sharp, snapping crackle effects at the tips, adding sharp audio texture and visual complexity to WTF's continuous canopy.

Coloured Peonies — full, round bursts of vivid coloured stars that spread in rich, symmetrical spheres across the sky in multiple colours, providing the most vivid and saturated colour moments across WTF's eight-cake sequence.

Glittering Stars — dense, glittering star bursts that shimmer and sparkle across the full sky, adding a fine, textured layer of light between the larger and more dramatic main effects.

Palm Bursts — radial explosions where thick comet tails sweep outward in multiple directions from a central detonation, creating the distinctive palm tree silhouette at height that is one of the most crowd-pleasing effects in consumer pyrotechnics.

The Finale — Rapid-Fire Shots of Colour That Just Keep Going

WTF's finale is described by display organisers and audiences alike as one of the most overwhelming experiences available from a single consumer compound firework. The closing cake fires in a relentless, maximum-pace rapid-fire sequence of coloured bursts that simply refuses to end — going and going and going until the sky is completely blanketed and the final shot exhausts the last of WTF's nearly 4kg of powder in one final, definitive crescendo.

What Makes WTF Different from Other High-Shot-Count Compounds?

Most high-shot-count compounds achieve their numbers through smaller tubes or reduced powder per shot. WTF takes the opposite approach — eight separate full-spec 64-shot cakes, each loaded to maximum capacity, pre-fused into a single compound. The result is that every one of WTF's 512 shots carries the full powder load and effect quality of a standalone premium barrage — there is no dilution of performance across the shot count. At 3,992g total powder across 20mm tubes firing in volleys of six, WTF delivers a consistency of impact across all 175 seconds that sets it entirely apart from competitors with similar shot counts but significantly lower NEC weights.

Safety Information

Minimum Safety Distance

WTF requires a minimum safety distance of 15 metres between the firing position and all spectators, structures, vehicles, and boundaries. While this is lower than F3 products with a 25-metre requirement, the 5 out of 5 noise level, 30-metre height, and 3,992g powder weight mean exceeding this distance wherever possible is strongly recommended. A practical recommended distance of 25 metres will significantly improve the viewing experience and safety margin.

Securing the Firework

WTF is constructed as eight pre-fused cakes mounted on a board — ensure the board is placed on firm, flat, level ground before ignition. Never place on uneven, soft, or sloped surfaces. The board format means staking is not required in the same way as a single boxed compound, but the firing surface must be completely stable and level before firing.

Hazard Classification & Category

WTF is classified as Hazard Class 1.3G, Category F3 — a professional-grade pyrotechnic. Despite its F3 category, WTF's 15-metre minimum safety distance makes it more accessible than many F3 compounds. Please ensure you are legally permitted to purchase and use F3 / 1.3G fireworks at your chosen location before ordering.

Frequently Asked Questions

How many shots does WTF by Vivid Pyrotechnics have?

WTF fires 512 shots in total — eight pre-fused 64-shot cakes that fire automatically in sequence from a single ignition point, with shots fired in simultaneous volleys of six throughout the entire 175-second performance.

How long does WTF last?

WTF has a duration of 175 seconds — two minutes and fifty-five seconds — of continuous, uninterrupted firing from a single ignition point, making it one of the longest-duration consumer compound fireworks available in the UK market.

What height does WTF reach?

WTF reaches a maximum height of 30 metres — among the tallest available in any 20mm tube consumer compound — delivering sky-filling burst coverage at a height clearly visible at large outdoor events and open fields.

What does firing in volleys of six mean?

WTF fires its 20mm tubes in simultaneous volleys of six shots, meaning six individual effects detonate at 30 metres height at the same moment. This effectively multiplies every single burst by six — creating a cluster of six overlapping effects per volley that produces far greater sky coverage and visual density than a single-shot sequence would achieve from the same calibre tubes.

What effects does WTF produce?

WTF produces brocades, golden willows, strobing dahlias, chrysanthemum crackles, coloured peonies, glittering stars, and palm bursts — spread across eight distinct pre-fused 64-shot cakes that each deliver their own effect set in sequence throughout the 175-second compound performance.

What is the safety distance for WTF?

WTF has a minimum safety distance of 15 metres — lower than many F3 compounds which require 25 metres — making it accessible to a wider range of outdoor spaces while still delivering 1.3G professional performance. A practical recommended distance of 25 metres provides an improved safety margin and better viewing perspective for the 30-metre burst height.

Can I use WTF in my garden?

WTF can potentially be used in a large garden with a minimum of 15 metres of clear space in all directions from the firing board, provided it is not in a noise-sensitive area and the 5 out of 5 noise rating is appropriate for your location. Given the 30-metre height and maximum noise level, a large open space such as a field or paddock will always provide a better and safer experience. Contact our team if you are unsure whether your space is appropriate.

How does WTF compare to other Vivid Pyrotechnics compounds?

WTF sits at the absolute top of the Vivid Pyrotechnics compound range, offering the highest shot count (512), the longest duration (175 seconds), and near-maximum powder weight (3,992g) of any single Vivid compound product. For smaller, more accessible options within the Vivid range, see Psycho (258 shots, 80 seconds) and Bloodshot (139 shots, 75 seconds) at Newsbox Fireworks.

Is WTF good value for money?

WTF consistently ranks as one of the best-value compound fireworks in the UK market on a cost-per-second and cost-per-shot basis. With 512 shots, 175 seconds of continuous firing, and nearly 4kg of powder weight, WTF delivers a display that would require multiple separate compound fireworks to replicate — all from one ignition point and one purchase.

Why is WTF called WTF?

The name is exactly what you think it is — and according to everyone who has seen it fire, it is entirely deserved. WTF is Vivid Pyrotechnics' way of promising that your reaction to the first volley will be involuntary, immediate, and entirely unprintable. Guaranteed.
