How to play Liquid lab
The screen is a glowing fluid simulation. Drag your finger or mouse across it to push the liquid around. Use the controls to bend gravity, switch colours, adjust the brightness, and change the simulation speed. There is no goal and no score, just a sandbox to play with. Tap reset to clear the canvas if it gets too busy.
Tips
- Quick swipes make crisp ribbons, slow drags make blobs
- Lower gravity for floating drift, raise it for waterfall vibes
- Try a single colour for elegance, mix for chaos
- Take a screenshot, the swirls only last a few seconds
About Liquid lab
Fluid simulations have been a staple of computer graphics research since the 1990s, with Jos Stam's Real Time Fluid Dynamics for Games paper in 2003 making them affordable for browsers. We took that math, dialled the colours up to glow, and added knobs for gravity, viscosity and hue. The result is a visual toy with no objective. Slap it on a second monitor for some calm in your day.
