🌍 SANDBOX — Elemental World

🧪 What is this?

Sandbox — Elemental World is a real-time particle simulation sandbox game. Place elements like sand, water, fire, lava, acid, and even antimatter — then watch them react, flow, burn, melt, explode, and interact in surprisingly realistic ways.

Every element has unique properties: density, state (solid/liquid/gas/powder), and reactions with other materials. The result is a living, breathing world that evolves right before your eyes.

🧬 Element Interactions (Some Highlights)

• 💧 Water flows down, puts out fire, dissolves salt, and turns lava into stone
• 🔥 Fire spreads to wood, oil, and gas — creates smoke as it dies
• 🌋 Lava melts snow, ignites wood, and reacts violently with water (→ steam + stone!)
• 🧪 Acid eats through sand, dirt, stone, wood, metal, and glass
• 🦠 Virus spreads to neighboring particles — can it consume your world?
• ⚛️ Antimatter annihilates anything it touches (except walls)
• 💥 Gas explodes into fire after a short fuse
• 🌱 Seed grows into plants when near water or dirt
• ☁️ Cloud drifts and rains water droplets below
• ⚡ Lightning strikes downward and conducts through water & metal
• 🧂 Salt dissolves in water
• 🪵 Wood burns → fire spreads through it
