Fluids
Soap Bubble
A soap bubble on a wand, with swirling rainbow colors, a film that drains and turns black at the top, and finally a pop; three glowing orbs swing around it painting ink on the film.
Drag on the film to swirl it, or stab fast to pop it; tilt to change which way it drains; tap after the pop for a new bubble. A finger on an orb carries and throws it.
- The idea
- The colors are real thin-film interference from the simulated thickness of the film, which flows with gravity and surface tension until it is thin enough to burst. The orbs follow a real three-body orbit.
- With music
- Kicks speed up the orbs; bass brightens their ink trails. Tap Demo beat for our own beat, or Your music to let it hear the room.
- How it runs
- It’s the same live simulation as in the Everdust apps, running in your browser on WebGL 2. If your device struggles, it lowers the detail a step at a time to keep the motion smooth.
This is just a taste
Loved Soap Bubble? There are many more worlds in the app.
The Everdust app has every world at full detail, plus games made of physics, stories you step inside, Create (turn any photo into a world), and hand tracking on Vision Pro and Quest. Free during the beta.
