Sand In a Box

Sand In a Box is a falling sand simulator where you experiment with materials such as sand, water, salt and acid, and observe how they interact.

Simulation tools

Thermal imaging lets you explore heat flow between materials. You can also conduct electricity through metals and observe its effects on other materials, such as using an electric heater to boil water. Radioactive materials let you observe elements’ half-life decay and their effects on surrounding materials.

Mods and custom elements

Modding support lets you create and share custom elements, change the game rules and explore content through a community-driven platform.
