About the scene
It is a festival night in a riverside park. Fireworks burst one after another above the city lights across the river, spreading bright reflections along the water.
Small groups sit on the lawn watching the fireworks. Some hold up their phones to photograph the sky, while stalls and food trucks by the water are brightly lit. Beyond the streetlights lining the path, the murmur of the crowd continues.
Each burst brings a different color and shape. Drag to slowly look around the riverside. There is no need to arrive early to find a spot or watch the fireworks surrounded by crowds.
The story of fireworks
Fireworks trace their origins to China, where gunpowder was invented. Before gunpowder, people put bamboo into fires to make it burst, believing the loud sound would drive away harmful spirits. Later, gunpowder firecrackers were developed. As the technology spread around the world, fireworks evolved into the colorful displays we see in the sky today.
The colors of fireworks depend on the metals they contain. Strontium produces reds, barium greens, copper blues, and sodium yellows. Vivid blue is known to be particularly difficult to produce.
Large fireworks contain small pellets of pyrotechnic material called “stars.” When a firework bursts in the air, these stars fly outward and glow. Their initial arrangement can create not only circles and rings, but also hearts and smiley faces.
From the Seoul International Fireworks Festival to Sydney’s New Year celebrations and summer hanabi festivals across Japan, fireworks mark festivals and special occasions in cities around the world. Countless people look at the same sky at the same time to see lights that disappear within seconds.

Frequently asked questions
Is this a video?
No. This is a scene generated in real time, rather than a prerecorded video. The scene never repeats in exactly the same way, and you can look around freely.
Can I use it on a phone or tablet?
Yes. You can use it on phones and tablets. Tap the screen to show the menu, and drag with your finger to look around.
If you plan to leave it running for a long time, we recommend keeping your device plugged in.
Why can’t I hear any sound?
Sound may be off when you first open a scene. Tap or click the screen once, then select the sound button in the bottom-left corner.
If you still cannot hear anything, check whether your device is in silent mode or the browser tab is muted.
Can I leave it running for a long time?
Yes. You can leave it running for a long time. When you switch to another tab or minimize the window, the scene pauses automatically while the sound continues.
To take a break, select the pause button. This pauses both the scene and the sound.
Why is the scene running slowly?
The scene may slow down or stutter depending on your device and other programs running at the same time. Try closing unused tabs or programs, then return to the scene.
It also helps to avoid running the same scene in several tabs at once.
What is the difference between theater mode and full screen?
Theater mode gives the scene more space within your browser. Full screen hides the address bar and menus to fill the entire screen with the scene.
Use theater mode while doing other things, or full screen when you want to focus on the scene.
