Fluids
Ferrofluid in Your Hand
A dish of black ferrofluid: bring a finger near and it rises into a field of sharp spikes that follow your finger.
Up to four fingers are four magnets: hold and drag them and the spikes follow. Tilt the device to pour the fluid.
- The idea
- Each finger is a magnet under the dish. The spikes are the real Rosensweig instability coming out of the simulated equations of a magnetic liquid layer, not a drawn pattern; you hear the magnet hum.
- With music
- It doesn't follow the music: it makes its own sounds, a magnet hum and the ticks of spikes forming. 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
