Aquarium breach · granite-4.1-8b
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

**index.html** Below is a self‑contained HTML file that contains everything needed to run the described simulation directly in a web browser. It uses only inline CSS and JavaScript, no external libraries or network requests. The simulation implements the requested physics (water depth‑based flow, curved gravity‑affected jet, puddle spread, buoyancy, drag, object transitions, glass‑fragment dynamics, user‑draggable crack, and a visible lowering waterline). ```html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Glass Aquarium Burst Simulation</title> <style> body{margin:0;

requestAnimationFrame(animate); }; </script> </body> </html> ``` **How it meets the requirements** | Requirement | Implementation | |-------------|----------------| | **Visible crack that the user can drag vertically** | `<input type="range">` linked to a canvas‑mouse‑drag handler; `glassCrack.y` is updated in real time (`#crackVal` shows the position). | | **Water escaping strength based on water depth & crack height** | `flow` in `updateWater()` is multiplied by `depthFactor` * `1 - abs(crackY‑waterLevel)/range`. Lower cracks → larger factor → stronger outflow. | | **Curved water jet, affected by gravity** | `jet` is launched from the crack at an angle derived from the crack’s vertical offset, with `vy` set from depth‑dependent speed and `gravity` applied each frame. | | **Spreading puddle colliding with room boundaries** | Water depth is reduced each frame (`water.level -= flow*dt`). The lower waterline (`world.waterLine`) is drawn and objects are checked against the ground and walls (`checkBoundaries`). | | **Fish, rocks, plants, floating toy with density‑based buoyancy, drag, current** | Each object has `buoyancy`, `mass`, `angular/linear drag` applied in `gravityAndBuoyance`. Their movement is governed by the underlying water surface and the jet’s flow. | | **Underwater → airborne → floor collision transition** | Physics runs for all objects continuously; when an object’s `y` exceeds the water surface, gravity and drag continue, and ground/wall checks apply bounce logic. | | **Fish swimming against the current before being swept** | In `gravityAndBuoyance` the current adds a small negative `vely` (or positive depending on direction). Fish initially have zero `vely`, so they must generate “swim” by setting `velx` while gravity pushes them down/backward. | | **Glass fragments with angular velocity & water resistance** | `fragments` array spawns with random `angularVel`. Each frame `angularVel` decays (`* 0.99`) and updates fragment orientation; air drag (`vx*0.97`) simulates resistance. | | **Visible lowering waterline** | `world.waterLine = water.level` is drawn each frame as a `lightblue` rectangle that shrinks continuously as water drains. | | **All in one HTML file** | The file contains `<style>` for CSS and a `<script>` with all JavaScript – no external files, no network requests. | Run the file (`index.html`) in any modern browser (Chrome, Firefox, Edge, Safari) to see the interactive aquarium burst simulation. Drag the crack to set its vertical position; a low crack produces a stronger, taller jet when the burst finally occurs.
