Virtual fireworks you can control
Use the full simulator to launch bursts, trigger finales, enter short text fireworks, and switch between manual and automated show modes.
Pyro Lab / online firework simulator
Online firework simulator for quick virtual fireworks
Launch fireworks in your browser, create short text fireworks, and switch between chemistry-inspired flame colors such as sodium yellow, barium green, copper blue-green, and strontium red.
- No download or account is required; the simulator runs directly in the browser.
- The full simulator includes sound, fullscreen mode, text fireworks, finale bursts, and performance controls.

What this page is about
A browser-based fireworks simulator
Pyro Lab is an interactive online firework simulator. The main experience is a canvas where you click or tap to place fireworks, choose color presets, and run a short virtual show without installing anything.
Flame-test color presets
Color options are named after common flame-test elements, giving the simulator a clear link to sodium, lithium, copper, barium, strontium, magnesium, and other metal colors.
Works as a quick celebration tool
Open it for holidays, countdowns, birthdays, classroom demos, idle breaks, or any moment that needs a small browser fireworks show.
Designed for desktop and mobile
The core interaction is simple: click or tap the sky. Detailed controls stay available without taking over the whole fireworks canvas.
How it works
From color choice to fireworks burst
The page content, navigation, and simulator controls all describe the same product: a free online firework simulator with virtual fireworks and chemistry-based color presets.
- 01
Choose a firework color
Start with a metal preset such as sodium, lithium, copper, barium, strontium, or magnesium.
- 02
Click or tap the sky
The canvas places each virtual firework where you interact, so the show feels direct and tactile.
- 03
Open the full simulator
Use sound, fullscreen mode, text fireworks, finale bursts, and performance controls for a larger show.
Color reference
Firework colors based on flame tests
Real fireworks often use metal salts to produce color. Pyro Lab turns that idea into simple simulator presets, so users can compare lithium red, sodium yellow, copper blue-green, barium green, strontium red, and magnesium white in one place.

Lithium
Li670.8 nmLithium produces a deep crimson red flame, one of the most recognizable flame colors.Sodium
Na589.0 nmSodium produces a bright yellow flame, the most common flame test reaction.Potassium
K766.5 nmPotassium produces a lilac/violet flame, best observed through cobalt blue glass.Calcium
Ca622.0 nmCalcium produces a brick-red/orange flame, commonly used in red fireworks.Strontium
Sr460.7 nmStrontium produces a vibrant scarlet red, the primary source of red in fireworks.Barium
Ba553.6 nmBarium produces a yellow-green flame, used in green fireworks.Copper
Cu510.6 nmCopper produces a blue-green flame, copper chloride gives a bright blue.Cesium
Cs455.5 nmCesium produces a blue-violet flame, the heaviest stable alkali metal.Magnesium
Mg518.4 nmMagnesium burns with a brilliant white light, used for flash effects in fireworks.Iron
FeMultipleIron produces golden sparks, used for gold spark effects in fireworks.Why this exists
Pyro Lab is a small browser experiment: part fireworks toy, part flame-color reference. It is meant to feel quick and a little tactile, not like a full production suite.
The canvas is the main control.
Start the simulator, then click where you want the burst to appear. The bottom panel is there only when you want to change the show.
The colors have a chemistry hook.
The presets are named after metals used in flame tests, so the color picker has a little bit of science behind it without turning the app into homework.
It stays intentionally simple.
No account, no editor timeline, no setup flow. Open it, pick a color, make a few bursts, move on.
