One step finer and one step more grains keeps the same sand. Finer grains need more substeps, so they cost more.

It pours like a fluid. It rests like a solid.
Friction resists sliding and lets a pile keep its slope.

• 1 camera · 2 rake · drag with one finger
• two fingers or right-drag orbit · scroll zoom
• Space pause · R restart this experiment
• Soft spherical grains with static / sliding friction. No grain rotation, angular shapes or wet cohesion.
