Aquarium breach · seed-2-1-turbo

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

For the user's single-file complex aquarium simulation, I'm planning features including a glass aquarium with water and a draggable side panel crack.

The full feature list for the aquarium simulation has been confirmed, and I'll use Canvas 2D for rendering to meet the single-file requirement. I'll build this project step by step.

Done! The simulation is in `/tmp/ws/index.html` — a single self-contained file with no external dependencies. **Features included:** 1. **Draggable crack** — Click and drag the yellow handle on the right glass panel to set the crack depth (5%–95%). Lower cracks = stronger jets. 2. **Curved water jet with Torricelli's law** — Flow velocity is `√(2gh)` based on water depth at the crack. The jet arcs under gravity and weakens as the water level drops. 3. **Spreading puddle** — Water particles hit the floor, settle into a puddle that spreads outward and collides with the right wall and aquarium base. 4. **Objects with distinct physics:** - **Rocks** (density 2.3–2.5): heavy, sink, barely move with current - **Rubber duck toy** (density 0.4): floats at water surface, drifts with flow - **Plants**: sway with current, anchored to the bottom - **Fish**: swim naturally, then **struggle against the current** before being swept through the breach, then become airborne, then flop on the floor 5. **Airborne & floor transitions** — All objects (fish, fragments, toys) properly transition from underwater drag → air resistance → floor bouncing with friction. 6. **Glass fragments** — 20+ jagged shards with random polygons, angular velocity, water resistance, and floor bounces. 7. **Continuous waterline** — The water surface lowers smoothly with a wavy surface, never disappears all at once. Click **💥 Burst Aquarium** to trigger the failure, **🔄 Reset** to try a different crack height.

EVALUATION

3/5 partial

Aquarium with fish, rocks, plants, and duck toy renders and animates, but no burst/crack/water jet triggered despite inputs tried.

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.
