Count every breath since you opened the page — and in a lifetime.
Paint sand, water and walls and watch the physics take over.
Launch colourful fireworks and watch them burst and fall.
Swirl beautiful ink-like fluid with real-time physics.
Move your cursor to bend a galaxy of orbiting particles.
Watch compound growth turn small savings into big numbers.
Tilt the gravity and watch thousands of droplets slosh around.
Generate endless random mazes — solve them or watch the solver.
Attract, repel and explode thousands of glowing particles.
Pour colourful sand and watch it pile into layered dunes.
A physics sandbox simulates how things move and interact. Instead of a fixed goal, you get a set of rules and the freedom to break them. Watching sand pile up, water flow or particles orbit is both fascinating and oddly calming, and it teaches real intuition about how the world behaves.
Particle Simulator reacts to your cursor with attract, repel and shockwave modes. Falling Sand is a pixel sandbox where fire burns wood, water spreads and plants grow. Gravity Simulator lets you bend the orbits of a miniature galaxy, and Fluid Simulation swirls colourful ink with real fluid dynamics.
Each simulation is deterministic enough to predict and chaotic enough to surprise. Change one slider and watch the whole system respond. It is a relaxed, hands-on way to explore physics that works for curious kids and adults alike.
Yes, every simulation runs free in your browser with no download and no sign-up.
They are built to run smoothly on modern phones, tablets and computers. Lower the particle count if your device feels slow.
They are a hands-on introduction to physics concepts like gravity, diffusion and fluid flow, so they work well in a classroom.
No — these are open sandboxes. Experiment freely and reset whenever you like.
