Interactive Fluids

Tilt, touch, and swirl a colorful particle playground. Explore fluid physics, customize your simulation, and play on iPhone, iPad, or Apple Watch.

Put fluid physics in your hands. Interactive Fluids is a particle playground for iPhone, iPad, and Apple Watch that responds to your touch and the way you move your device. Tilt, turn, and move your device to send particles flowing across the screen. Touch and swipe to push them around, carry them with your finger, or stir things up with Big Wiggle. Make the simulation your own: • Add particles or remove fluid. • Change colors and explore different simulation modes. • Choose Repel, Carry, or Big Wiggle touch controls. • Experiment with up to 10,000 particles. • Play directly on Apple Watch, even without your iPhone nearby.
