I'll create a comprehensive physics simulation of a glass aquarium with a crack that bursts. This will include realistic water physics, object interactions, and fluid dynamics.

I've created a comprehensive physics simulation of a glass aquarium with a crack that bursts. Here's what the simulation includes: ## Features Implemented: **Water Physics:** - Water escapes through the crack with flow strength based on water depth (Torricelli's law) - Curved water jet affected by gravity - Spreading puddle that grows and collides with room boundaries - Visible waterline that lowers continuously as the tank drains **Objects with Realistic Physics:** - **Fish**: Swim against currents, affected by buoyancy and drag, attempt to escape the breach - **Rocks**: Sink due to high density, tumble with angular velocity - **Plants**: Sway in water currents, float when airborne - **Floating Toy**: Bobs on surface, affected by buoyancy **Object Transitions:** - Objects correctly transition from underwater → airborne → floor collisions - Different behaviors based on density, buoyancy, and drag coefficients **Glass Fragments:** - Angular velocity and realistic collisions - Water resistance when submerged - Scatter when the tank bursts **Interactive Controls:** - Drag the crack handle vertically before triggering - Lower cracks produce stronger initial jets (higher water pressure) - "Trigger Burst" button to initiate the failure - "Reset Simulation" to restart **Visual Elements:** - Realistic water rendering with gradients and surface waves - Glass tank with transparency effects - Room environment with floor and walls - Color-coded objects for easy identification The simulation runs entirely in the browser with no external dependencies. The physics engine handles gravity, buoyancy, drag, collisions, and fluid dynamics to create a realistic catastrophic failure scenario.
