Aquarium breach · gemini-2.5-flash-lite

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
