⚡ SANDBOX — Advanced Physics

A Living, Breathing Particle Physics Playground

Unleash your inner scientist with this fully interactive physics sandbox. Create, destroy, and experiment with over 30 unique elements in a dynamic environment where temperature, pressure, gravity, and convection work in real-time.

SANDBOX is an advanced particle physics simulation that puts the power of a laboratory at your fingertips. From simple sand and water to reactive fire, corrosive acid, and explosive gas — every element behaves with realistic physics. Watch as heat spreads, liquids flow, plants grow, and chemical reactions unfold before your eyes.

🌌 The Premise

Imagine a world where you control the laws of physics. A blank canvas where you can sculpt mountains, create rivers, ignite forests, and trigger chain reactions — all with the click of a button. SANDBOX is that world.

This is not just a game. It's a physics engine, a creative tool, and a scientific playground rolled into one.

🧪 Gameplay

🌡️ Elements & Interactions

With over 30 unique elements, the possibilities are endless:

Natural Materials

• 🟡 Sand — Falls and flows like real granular material
• 💧 Water — Fluid dynamics with realistic flow and buoyancy
• 🟫 Dirt — Soft, diggable terrain
• ⬜ Stone — Hard and durable, can be melted into lava
• 🔘 Gravel — Loose, falling material
• ❄️ Snow — Light, melts into water
• 🧊 Ice — Solid water, melts when heated
• 🌱 Seed — Grows into plants over time
• 🪵 Wood — Flammable, burns into fire

Fire & Gas

• 🔥 Fire — Spreads, burns fuel, and generates heat
• 🌋 Lava — Melts stone, ignites wood, vaporizes water
• 💨 Smoke — Rises, dissipates over time
• ♨️ Steam — Gas phase of water, rises and condenses
• 💥 Gas — Explosive, ignites and expands

Liquids

• 🧪 Acid — Corrodes most materials
• 🛢️ Oil — Flammable, floats on water, ignites

Special Elements

• 🦠 Virus — Spreads to nearby particles
• ⚛️ Antimatter — Annihilates anything it touches
• 🔲 Glass — Transparent, melts at high temperature
• 🔩 Metal — Strong, conducts heat
• 🧂 Salt — Dissolves in water
• ☁️ Cloud — Floats, produces rain
• ⚡ Lightning — Damages materials, creates fire
• 🔄 Clone — Copies nearby materials
