Aquarium breach · gemini-3-flash-preview
Create a large glass aquarium whose side panel develops a visible crack and then bursts. The simulation must include: - Water escaping through the opening with flow strength based on water depth and decreasing as the tank drains - A curved water jet affected by gravity - A spreading puddle that collides with the room boundaries - Fish, rocks, plants, and a floating toy reacting differently according to density, buoyancy, drag, and current - Objects transitioning correctly from underwater motion to airborne motion and then to floor collisions - Fish attempting to swim against the current before being swept through the breach - Glass fragments with angular velocity, collisions, and water resistance - A visible waterline that lowers continuously rather than disappearing all at once Let the user drag the crack vertically before triggering the failure. A lower crack should initially produce a stronger jet than a higher crack. Give me 1 html file

**Simulating the Bursting Aquarium** I'm focusing on developing the core mechanics for the aquarium simulation. My current efforts are directed towards implementing the interactive crack, allowing vertical dragging, and initiating the bursting sequence once that crack is manipulated. The water physics will follow. **Modeling Water Dynamics** My current focus is on refining the water physics following the initial crack interaction. I'm implementing Torricelli's Law to govern water jet strength based on depth, and considering the curved trajectory gravity will impart. I'm also planning for a realistic spreading puddle effect on the floor. **Refining Water Simulation** I'm now refining the water simulation, focusing on the discrete update of the water level based on the outflow rate. I'm also developing the physics for how various objects like fish, rocks, and plants will react to the water current and gravity once the tank breaches.

**Refining Physics and Effects** I'm focusing on enhancing the physics for all objects – fish, rocks, plants, and toys – to ensure their interactions are more robust and visually apparent. Additionally, I'm aiming to make the water jet's trajectory more distinct.

**Implementing Core Physics** I've successfully integrated the fundamental physics and visual elements. The aquarium is rendered, complete with a visible crack that now dynamically bursts. Water is escaping, with its flow accurately simulated based on depth according to Torricelli's law. **Refining Dynamic Interactions** I've successfully implemented the water jet and spreading puddle, with objects and environment elements reacting realistically. Transitions from underwater to air are handled, and fish now contend with currents. Glass fragments are flung with angular velocity, and the waterline visibly recedes. User interaction with the crack is functional.

**Fixing render logic** I've identified an error in my previous `oldText` for the `render` function edit. I'll correct that and re-apply the `drawTank` changes to ensure accuracy.

**Applying Enhancements** I've clarified the file structure and will now re-apply the necessary enhancements to the `drawTank` and `render` functions. My focus is on correcting the object rendering order so that interior elements appear behind the water and frame, while exterior elements are drawn atop them. I am proceeding with these edits.

**Completing Simulation Refinements** The simulation is now finalized and satisfies all user specifications. I've integrated physics-based interactions, dynamic crack placement, and a visual sequence for the tank rupture.
The aquarium burst simulation is now complete in a single self-contained HTML file. ### Key Features: - **Interactive Crack**: Before clicking "BURST", you can drag the red indicator on the right side of the tank to position the crack. - **Pressure-Dependent Flow**: The jet's initial velocity is calculated using Torricelli's Law ($v = \sqrt{2gh}$), meaning a lower crack produces a stronger, further-reaching jet than a higher one. - **Dynamic Water Level**: The waterline lowers in real-time as water escapes, and the jet's strength diminishes as the water pressure drops. - **Physics-Based Objects**: - **Fish**: Attempt to swim away from the suction of the breach until the current becomes too strong, at which point they are swept out. They transition from swimming to "flopping" on the floor. - **Rocks**: High density; they sink and mostly stay put unless the current is extreme. - **Plants**: Tethered to the bottom; they sway with the current and can be ripped out if the flow is high enough. - **Toy Duck**: Low density; it floats on the surface and is eventually carried out by the surface current. - **Environmental Effects**: - **Glass Fragments**: Shard-like polygons fly out upon bursting with random angular velocities. - **Spreading Puddle**: Water accumulating on the floor expands until it hits the room boundaries. - **Gravity & Drag**: All entities transition seamlessly from buoyancy-driven underwater physics to gravity-driven air physics and floor collisions. ```html <!-- Final file: index.html --> ```

Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
