What is SandLab?

SandLab is a falling-sand physics sandbox with over 270 materials that react to each other on their own. Pour sand, flood it with water, drop lava into the lake and watch it hiss into steam and harden into stone. Acid eats through metal, current runs along wires, plants grow toward water, gunpowder goes boom.

Set up the room the way you want: change the temperature from deep space cold to blazing heat, turn gravity down, off or upside down, add wind and speed up heat flow. Presets like Moon, Arctic, Inferno and Upside down are one click away.

Discover all 199 reactions and fill your lab notebook. Short goals teach the basics and point you to new experiments: boil water, grow a plant, make glass, light a lamp, bake bread, forge bronze.

Features:

• 270+ materials: powders, liquids, gases, metals, chemicals, food, life and special elements like cloner, void and black hole
